struct.error on Mac OS X

[lrowe]

Running with python 2.7 from python.org on Mac OS 10.6 I get the following error packing a simple "Hello, world!" script.

$ cat test.py 
print "Hello, world!"
$ bb-freeze test.py 
*** applied <function recipe_doctest at 0x101218938>

you can try upgrading macholib. Other than that I won't help you here since I lost all interest in supporting OS X. I will accept patches however...

macholib is gone from bbfreeze 1.0. that specific error shouldn't happen anymore, but freezing on OS X is most probably still broken.
