[sugar] Sugar Python environment

I'm thinking that the Sugar jhbuild should probably use 
virtual-python.py: http://peak.telecommunity.com/dist/virtual-python.py

Alternately (and particularly if OLPC goes to Python 2.5), Python should 
be built as part of the build process.  virtual-python basically 
symlinks Python so it doesn't pick anything up from the global 
installation.  It's like building a custom Python, but faster since it 
doesn't actually build anything.

Then instead of relying on $PYTHONPATH to control the environment, using 
build/bin/python will use the custom environment.  (And of course, 
having that directory first on $PATH will make "python" work as well.)

Would building 100% of the OLPC software be prohibitive (either to build 
the software, or setup the build process)?  That would then give us a 
completely accurate system and process.

Almost unrelatedly, I think Python 2.5's enhanced generators 
(http://www.python.org/dev/peps/pep-0342/) could be syntactically 
appealing for doing async DBUS messages.  I just mention this as another 
point in 2.5's favor, and because it occurred to me just now.
