Oops, I saw that part, but just didn't think clearly enough when I replied.
Let me try again:

File imptest.py, compiled with py2exe as imptest.exe:

import sys
sys.path.append('c:/temp')
filename = sys.argv[1]
try:
    mod = __import__(filename)
    print mod.test()
except:
    print 'test failed!'


File importme.py, stored in c:/temp, containing

def test():
    return 'test OK!'


Run imptest.exe from a directory other than c:/temp:

"test OK" results.

Looks like it works...  (I'm doing this test first... what did I do
wrong this time?  :-)
