AxKit configuration question

Hi All,

I'm attempting to install AxKit 1.4 (and 10 or so other pre-requisite
modules) on my modperl/modssl server, and I'm trying to get the
ultra-basic AxKit manpage example to work ('perldoc AxKit').  

The first sign of trouble has arisen:  httpd silently exits immediately
after startup once I add the specified AxKit configuration to my Apache
config files, and I have not been able to find any logging whatsoever
yet.  I can see it is successfully loading AxKit.pm, and producing
seemingly all of the normal Apache log startup messages I usually see. 
It's just that when I go to the ps table, it is not there.  Does anyone
have a clue to offer before I recompile with debugging on?

My server's status line is 

  Apache/1.3.20 (Unix) mod_perl/1.25 mod_ssl/2.8.4 OpenSSL/0.9.6b

(it once had AxKit 1.4 in it, but I haven't been able to reproduce
that...)
 
Here's my httpd.conf file:

##################################
<IfModule mod_perl.c>
    Include conf/perl.conf
</IfModule>
##################################

Here's part of conf/perl.conf:

#######################################
PerlModule AxKit

<Location /ax>
    # Install AxKit main parts
    SetHandler perl-script
    PerlHandler AxKit

    # Setup style type mappings
    AxAddStyleMap text/xsl Apache::AxKit::Language::Sablot
    AxAddStyleMap application/x-xpathscript \
           Apache::AxKit::Language::XPathScript

    # Optionally set a hard coded cache directory
    # make sure this is writable by nobody
    AxCacheDir /opt/axkit/cachedir

    # turn on debugging (1 - 10)
    AxDebugLevel 10
    AxStackTrace On
    AxLogDeclines On
</Location>
######################################

If I delete this section of perl.conf, the server starts and runs fine,
albeit without the desired AxKit effect!!

The only thing I have not investigated are a bunch of log messages re
Apache::Status as follows ...

Subroutine menu_item redefined at
/usr/lib/perl5/site_perl/5.005/i386-linux/Apache/Status.pm line 46.

and a bunch for mod_perl.pm ...

Subroutine Apache::Table::TIEHASH redefined at
/usr/lib/perl5/site_perl/5.005/i386-linux/mod_perl.pm line 65535.

Thanks in advance for any clues/pointers.

Yes, I tried on someone's suggestion earlier, but without success. 
Axkit.org is still down (I think Matt Sergeant is still in the process of
relocating).  Thanks for your suggestion, though.  I do have a few
avenues to explore further.

have you tried disabling expat compiltation into apache?
as detailed here:
http://axkit.org/faq.xml
under "I install AxKit and Apache segfaults when it starts".

Just to ensure that Apache was compiled without expat, does
    grep -i xml /usr/local/apache/bin/httpd
match? Also, are all required modules, especially XS-based
ones like libapreq, compiled against the same mod_perl/apache
sources as AxKit was?

I tried it without SSL, and the same problem remains:  httpd exits
silently after seemingly normal startup.  I'll try 1.5RC, axkit irc, and
debugging if I can't find a way around in my laziness.  Thanks.

It's supposed to, but sometimes apparently it doesn't (I haven't been able to 
track down why, and it may be my fault).

Have you tried without SSL ? It sometimes conflicts with other modules. 
Another search track would be to find out which module that AxKit pulls in 
causes the crash (if any). You could also try out the 1.5 RC (which must be 
called 1.4_9x and is probably on CPAN or mirrored somewhere), it's been quite 
stable in my experience.

I don't think so, not the way I tried it, anyway...

cd $SSL_SRC_DIR/$MOD_PERL_DIST
perl Makefile.PL \
    USE_APACI=1 EVERYTHING=1 \
    DO_HTTPD=1 SSL_BASE=/usr/local/ssl \
    APACHE_PREFIX=$SSL_LOCAL_DIR \
    APACHE_SRC=../$APACHE_DIST/src \
    APACI_ARGS='--enable-module=ssl, \
                --enable-module=rewrite, \
                --enable-module=perl, \
                ...
                --disable-rule=expat'
(make && date && make test && date && make install && date) | tee
make.log
cd $SSL_SRC_DIR/$APACHE_DIST
make certificate TYPE=custom
make install

There's also a note (in AxKit 1.4 change log, I think) that says that
problem is fixed in 1.4.  Also, from 'perldoc AxKit':

       If you have a recent mod_perl and use mod_perl's
       Makefile.PL DO_HTTPD=1 to compile Apache for you, this
       option will be enabled automatically for you.

Other clues?

The AxKit FAQ (which unfortunately I don't think is reachable yet
at http://www.axkit.org/) says that there could be some problems
with Apache's default build with expat enabled and XML::Parser's
version of expat. The recommendation is to recompile Apache
with --disable-rule=expat. Does this work?

More data:  there is no core file created, and the mere presence of this
one line in my httpd.conf ...

	PerlModule AxKit

...with no other AxKit directives anywhere, causes httpd to exit shortly
(< 1 sec) after starting.  I hacked AxKit.pm to verify it is loading, and
it is successfully completing it's BEGIN block.

Any clues?
