Thanks, that's very useful. And it explains why Python Math wants to rewrite the .pyc files: imp.get_magic() returns (null) whereas on my Mac where I compiled them, get_magic() returns '\x03\xf3\r\n'.
Now I just have to figure out why I'm getting nothing useful from get_magic(). I assume this would have to be fixed to try solution 1), i.e., leaving out the .py files and delivering only the .pyc. Terry -- http://mail.python.org/mailman/listinfo/python-list
