[gentoo-user] Perl server-side debug

I have a non-gentoo question here, but my problems are probably partly
flavored by using gentoo at home and something else at work.

Here is a page on debugging perl server-side code under Apache:

    http://perl.apache.org/docs/1.0/guide/debug.html#Interactive_mod_perl_Debugging

It has two steps: starting apache with -X (run on the console in the
foreground, don't fork or start any children, handle incoming requests
directly one at a time) and adding configuration to use Apache::DB.

My problem is that I am trying to do this on a server not entirely
under my comlete control; it writes a configuration file from a
template which I can change, but a lot of internal logic deals with
Mason, and I can't just go changing everything to make this work.  I
can start my own server, that is not the problem, it's that I must
keep its original behavior intact, including using Mason.

One of the puzzles is that the web page in question apparently is
using a pretty old version of perl5db.pl, 1.0402, which has different
perldb commands than I am used to: 'w' for a "window" of source
listing, where I am used to 'l' for "list".  Both my home gentoo
system and this foreign system I am using are 1.28.

Or perhaps this web page is written for Windows users of some sort,
and Windows perl has differences from the real version :-)

Does anyone have any experience with this server-side debugging process?
