Trouble with make source_scan


Hello,

I wanted to add some functionality to mod_perl. I am following the
'mod_per 2.0 Source Code Explained' guide. Before doing any change at
all I tried to run 'make source_scan' and I got some errors.  Going
through build/source_scan.pl I was able to tell which errors where
generated from each instruction (see below), but this has not brougth
me any further. Can anybody give me a hint about what I could do?

Thanks!

mod_per: 2.0 (checked out from CVS, Nov 26 2002)
perl: 5.8.0

$p->write_structs_pm complains the following:
----------------------------------------------------------------------
failed on <










    enum {

        APR_BUCKET_DATA = 0,

        APR_BUCKET_METADATA = 1
    } is_metadata;> with type=<>, id=<enum>, post=<> at pos=25
----------------------------------------------------------------------


... and $p->write_functions_pm complains the following:
----------------------------------------------------------------------

It's not working most of the time, as Apache source gets changed all the 
time. You need the patched Scan.pm from apache.org/~dougm/, but it 
doesn't seem to work for me with the latest cvs.

Hopefully Gerald Richter gets his generalized version to work asap, so 
we don't rely on C::Scan anymore.

When the scan doesn't work, you should manually add the functions to 
xs/tables/current/, which is pretty easy to do if you don't have many of 
them.

And if you have some improvements to the scarce notes in the 'mod_perl 
2.0 Source Code Explained' chapter, please send me a patch... thanks.
