This is intentional -- it prevents people from *relying* on the case
matching to make their program work.  (The case sensitivity is there
to make your program fail if you typed "import String" when you meant
"import string".)

Two workarounds: (1) make a copy of the second one with a different
name, and use that; (2) rearrange your sys.path so that the one you
want to use comes first.  Neither might work if you have some library
module that uses one and some other library module that uses the other...
