Thanks for your reply!

What I am trying to achieve here is to have a patched modules directory that could contain the patched versions of modules that are there in the deployed code. If there is a module in the patched library directory, it should be picked up over the one in the deployed code and if not, things should work fine with just the deployed code.

So I am not sure how to load them before loading the others since the module names are the same and only the locations differ. Also if I load them using use, I guess I will have to run use lib before every use statement. :-/
