Apache::DProf

I have troubles using Apache::DProf
I try to use it as described at:
http://perl.apache.org/docs/1.0/guide/performance.html#Code_Profiling_Techni
ques

But when my httpd.conf has a line:
    PerlModule Apache::DProf
apache reply with error 500 (Internal Server Error) when I request a perl
script, that runs under mod_perl

Without this line, all works fine!

Errorlog shows following message during each request:
[Sat Jul 20 07:34:28 2002] [error] Undefined subroutine
&Apache::Registry::handler called.


I have in my httpd.conf
<Files *.pl>
  SetHandler  perl-script
  PerlHandler Apache::Registry
  PerlSendHeader On
  Options +ExecCGI
  PerlModule Apache::DProf
  PerlRequire /path/to/my/modules/modperl_startup.pl
</Files>

Is here something wrong?
How can I have Apache::DProf worked for profiling my code?

Thanks in advance.

Think you need to load in Apache::Registry with :

PerlModule Apache::Registry

before the PerlHandler Apache::Registry bit
Suggest also that you do all the module loading / startup before specifying 
any handlers

eg . from my mod_perl.conf

        PerlRequire             conf/startup.pl
        PerlFreshRestart        on

        PerlSetVar StatusOptionsAll On
        PerlSetVar StatusTerse On
        PerlSetVar StatusTerseSize On
        PerlSetVar StatusTerseSizeMainSummary On

        Alias /perl-bin/ /usr/local/apache/mod_perl/

        PerlModule Apache::DProf
        PerlModule Apache::Registry
        PerlModule B::TerseSize
        PerlModule Apache::Status

        <Location /perl-bin>
                SetHandler perl-script
                PerlHandler Apache::Registry
                Options ExecCGI
                PerlSendHeader On
                allow from all
        </Location>

Thanks, Ilya! You are right!
/usr/bin/perl contains old binary from v5.00503
So, I've change it to a link pointing to /usr/local/bin/perl
Now all works fine!

Looks like your sys admin had installed perl from core and from ports
and as result you have two perl installation on systems. Perl from
core (5.00503) likely to have is binary in /usr/bin/perl and perl from
ports (5.6.1) in /usr/local/bin/perl.

If your PATH doesn't have /usr/local/bin or it comes after /usr/bin
than 'perl Makefile.PL' uses perl from core. Try either changing your
PATH or using full path to perl (i.e. /usr/local/bin/perl
Makefile.PL).
