Hi.

First, you should probably pay more attention to what Perrin tells you, 
rather than to what I tell you below.  He is the real expert, I just dabble.
So you should probably first verify the version of Perl on your system, 
and maybe try an update of that, before you look at what follows.

This being said, I also manage two Debian systems of slightly different 
versions, and because of the different Debian package levels available I 
have to maintain at the moment a different mod_perl startup script on 
each.  The point is that, at some precise level of mod_perl versions 
(1.99xx, I don't remember exactly but you can find out on 
http://perl.apache.org), the names of many modules changed, from 
Apache:: to Apache2::.
(It is annoying, but the new naming is much cleaner, so it's better in 
the long run).
Below I show my two startup scripts.  Probably not all of that applies 
to you, but it may be worth verifying.

mod_perl 2.x (more recent Debian version)

# Apache2 / mod_perl 2 startup script

   use Bundle::Apache2 ();
   use Apache2::compat ();
   use lib "/usr/local/lib/apache2/perllib";
   use ModPerl::Util ();
   use Apache2::RequestRec ();
   use Apache2::RequestIO ();
   use Apache2::RequestUtil ();
   use Apache2::Filter ();
   use Apache2::ServerUtil ();
   use Apache2::Connection ();
   use Apache2::Log ();
   use Apache2::Const -compile => qw(:common :log REDIRECT);
   use APR::Const -compile => ':common';
   use APR::Table ();
   use ModPerl::Registry ();
   use CGI ();
   CGI->compile(':all');
   1;


mod_perl 1.9x (older Debian version)

# Apache2 / mod_perl 2 startup script

   use Apache2 ();
   use Apache::compat ();
   use lib "/usr/lib/apache2/perllib";
   use ModPerl::Util ();
   use Apache::RequestRec ();
   use Apache::RequestIO ();
   use Apache::RequestUtil ();
   use Apache::Filter ();
   use Apache::ServerUtil ();
   use Apache::Connection ();
   use Apache::Log ();
   use Apache::Const -compile => qw(:common :log REDIRECT);
   use APR::Const -compile => ':common';
   use APR::Table ();
   use ModPerl::Registry ();
   use CGI ();
   CGI->compile(':all');
   1;

Note : I do not remember why in the first script I "use 
Bundle::Apache2", and not in the second.

Hope this helps,
André

P.S.
And, by the way, if one of the experts here knows a better/cleaner way 
than the above, please let me know.
