I have Pyside 1.2.1 as follows:

Gregs-MacBook-Pro-2:PySide-1.2.0 Greg$ ls
MANIFEST.in popenasync.py setup.cfg
PKG-INFO pyside_build setup.py
README.rst pyside_install sources
pycache pyside_package utils.py
distribute-0.6.45.tar.gz pyside_postinstall.py
distribute_setup.py qtinfo.py
Gregs-MacBook-Pro-2:PySide-1.2.0 Greg$

PyQt4 is installed and works, as does Python 3.3. However when I $ python3 setup.py install I get......

In file included from /Users/Greg/Downloads/PySide-1.2.0/sources/pyside/plugins/customwidgets.cpp:23:

What am I doing wrong? This is very frustrating as PySide and PyQt4 works on my windows desktop under eclipse ; PyQt4 works on my MAC under eclipse, yet PySide does not. I need to do both in order to prove the cross-platform capability of PySide.

Your help would be appreciated.

PS I am new to this game, so clear instructions on how to resolve this problem would be most appreciated.

Many thanks in advance.

Greg
