[Tutor] cannot convert eps to png using PIL

[Chris Fuller]

It's trying to launch GhostScript, and failing.  The broken pipe is a clue 
that its trying to communicate with external software.  Most likely, you 
don't have ghostscript installed.  Google Ghostscript and you should find 
instructions for installing on windows (I'm fairly sure there is a port).  As 
for getting it to work with PIL, I'd just try getting it on your path 
(os.environ['PATH'] should work, too).  But you want to talk to the 
GhostScript folks; this isn't a Python problem, and there isn't an alternate 
solution that is more Pythonic.

Cheers
