based on everything that philip mentioned, my guess is that the
modules are not being imported correctly

personally, i solve lib issues in mod_perl as such: i have a 'use
lib' line in startup.pl that calls in my handler lib, and various
external libs

----
use lib qw(
/webserver/sites/FindMeOn.com/web-modperl/lib
/webserver/sites/FindMeOn.com/web-modperl/lib-externals/Authen-
PluggableCaptcha/lib/
/webserver/sites/FindMeOn.com/web-modperl/lib-externals/Apache2-
xForwardedFor/lib/
/webserver/sites/FindMeOn.com/web-modperl/lib-externals/P_2XLP
);
----

thats in the startup.pl file for my local machine.
my production box is freebsd, which has root in /usr/local/www/sites/
FindMeOn.com/web-modperl
