On Mac OS X the paths to the files are so long as to make the 
tracebacks really ugly and *less* usable.  I certainly wouldn't mind if 
__name__ showed up instead of __file__.  I have a "pywhich" script that 
shows me the file given a name that I use:

(note that modulegraph.util.imp_find_module is like imp.find_module but 
it will walk the packages to find the actual module and it only returns 
the filename)

#!/usr/bin/env python
import sys, os
from modulegraph.util import imp_find_module
for module in sys.argv[1:]:
     path,oext = os.path.splitext(imp_find_module(module)[1])
     for ext in ('.py', oext):
         if os.path.exists(path+ext):
             print path+ext
             break
