Most of the time (but not always) the problem is that py2exe copies
system specific dlls to the dist folder.  What files do you have there?
Or could it be that the target machine doesn't have msvcrt.dll (which is
needed by the Python dll, but not copied by py2exe).

(Un?)fortunately I have no access to winME...
