Hey Eric,

I empathize with you! Getting myself up-to-speed with mod_perl development 
has been a demanding task. At the moment, my apps have stabilized but I'm 
sure to hit another hurdle down the road.

As for Apache::DB, read the mod_perl guide at perl.apache.org. The 
debugger is a pain to learn but has helped me to solve several problems. 
There is good documentation on using the debugger in the camel book as 
well. One trick I learned was to let the script run through once using the 
'c' command. That will load all the scripts and modules into memory which 
will let you set breaks in your code without having to watch every line go 
by.

Also, I noticed some folks pointing out some global variables. If you're 
having troubles tracking these down in your script, you can see all the 
variables your script has instantiated by using perl-status and looking at 
the Loaded Modules. Find your CGI::App module in the list and click it to 
get a detailed list of the arrays, functions, hashes, etc. that it loads.

Good luck,
William
