And as I'm sure you realize, those two impression slightly contradict
each other.  Anyway, a small modification to my second approach would
also work in the case looking for packages in a directory that's
located somewhere relative to the one where the script was found:

if __name__ == '__main__':
    import sys, os.path
    base = sys.path[0]
    for d in 'lib', 'modules':
        d2 = os.path.join(base, d)
        if os.path.isdir(d2):
            sys.path.append(d2)
    base = os.path.join(base, '..')
    for d in 'modules', 'lib':
        d2 = os.path.join(base, d)
        if os.path.isdir(d2):
            sys.path.append(d2)
    # for debugging
    print repr(sys.path)

(BTW, this is such a fun script to type.  My fingers keep typing
'os.path' where I mean 'sys.path' and vice versa.)
