Before I try it, I want to see if anyone has any insights.

I want to install version 2.0 of a perl module into a local directory. The concern is that version 1.0 of the same module already exists in the main PERL directory that I do NOT have write-access to.

Of course, I could always contact the system admin to upgrade the module, but I reckon it would not be high on his priority list.

In my script, I am using a standard header subroutine to pull in modules from both my local directory and the main PERL dir.

I am using a "use lib" statement for each directory, thus, what will @INC contain if it sees the same module name twice?

Are multiple "use lib" statments somehow prioritized, that is, will the last imported instance of a module overwrite any of those previously imported, or vice-versa?

I'm sure this same issue will arise again in the future. Any other ideas(not involving the sys admin) on what I can do?

Is their great risk of crashing anything? Mind you, I am doing this at work.
