I had just added a library function to my general use library when I suddenly started getting a redefined subroutine warning for File::Basename (see below) from a program that had been running warning free until that moment. Both the main program and the new library function specify use File::Basename.

That should not be a problem if your library declares a package name. Don't make perl4-style libs that just dump all their functions into your main program -- you will regret it.

It was always my understanding that use and require would not try to load a module a second time if it was already listed in %INC.

They will still call import() a second-time though.
