The binhex module only understands resource forks if os.name == 
'mac', which is only true for CFM builds of Python.  We haven't 
maintained those in years, so this has been broken for quite some 
time.

This patch is a partial fix that allows it to de-binhex the resource fork 
on Mach-O, but it still doesn't do the type/creator stuff.  I'm currently 
only using it to create one of those pesky "Icon\r" files, so this is all 
I fixed and tested.
