[Pythonmac-SIG] py2app warning: may need to include email.Util

[Russell E Owen]

My py2app-bundled Mac application recently started failing with "no 
module named email.Util" when trying to display images. It turns out 
pyfits uses urllib which uses email.Util, which apparently has been 
renamed email.util with some kind of clever lazy import code so one can 
still use email.Util. Apparently the cleverness is too much for py2app's 
module finder.

Anyway, the easy workaround is to specify email.Util as a necessary 
module to import. But I'll report a python bug or submit a urllib patch.
