we have copied the perl folder from test box to production. in production it is supposed to be edms and in test it is qedms

Oh ... I think I get it now. You've built a perl on one machine that looks for (and finds) the modules in the "qedms" folders.
Then you've copied that perl to another machine and renamed the "qedms" folders to "edms". Perl still tries to find the modules in the "qedms" folders (because that's the way its @INC was constructed), but now perl can't find any modules because the folders it searches are non-existent.

How do you want to fix this ? Simplest way would be to rename the "edms" folders back to "qedms" on the production machine.

Cheers,
