[PySide] help: can't install Pyside on linux anymore

Hey Frank,

I don't know about the linux part but you can keep PySide on a central 
server, just don't add that path to you PYTHONPATH by default. Nuke does 
not need to know about it, but in a standalone app you could just do 
something like:

import sys

and that one works again.

The strategy I am going for here is: All standalone apps use the 
standard (Windows) Python and standard installers for packages.
We have a lot of compiled dependencies  like PyQt, ZeroMQ or MySQL in 
Maya/Nuke/Houdini. The path.add method is the way I manage those to 
dynamically "mount" (i.e. path.add) all the packages I need per host 
program (with their own compiler version, because thats where the 
problem comes from)
