I'm building a web application using perl, apache2 and mod_perl2. I'm experiencing some weird stuff. When I run the app from the console, it works fine. Also using perl cgi instead of mod_perl it works fine.

When I use mod_perl I get a not found error, on the first "use"d module. All the modules are in the same dir as the .pl script, /www/domain/cgi-bin/.

When I insert "use lib '/www/domain/cgi-bin';" in the script, the app works fine. But I rather not have hardcoded paths in my script, that's what config files are for.

I tried to overcome this issue by using FindBin and FindBin::Real, and using the $0 var. But without success. The bizarre thing is that the following works:

use lib "/www/domain/cgi-bin";

but the following does NOT work:

my $path = "/www/domain/cgi-bin";
use lib $path;

and that freaks me out.

Could anyone shed some light on this please?
