<![CDATA[Installation problem]]>Running the post-install script generated a runtime error. No idea what it means. I had previously installed PySide. Did uninstall of PySide and was reinstalling. Could be the symlinks still existing in /usr/lib cause this.

There is no clean way to uninstall. It might shock you that sometimes that is necessary. It would be nice if you supplied an uninstall script. I don't know where all the pieces land.

Here is the runtime error:
PySide package found in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PySide...

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "simple.py", line 7, in <module>
from PySide import QtGui
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PySide/QtGui.so, 2): Library not loaded: libpyside-python2.7.1.2.dylib
Referenced from: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/PySide/QtGui.so

But, this really doesn't make sense. In /Library/Frameworks/Python.framework/Versions/2.7/python2.7/site-packages/Pyside we find:

So, must be some weird path thing.

Python sys.path is:

['',
'/Library/Frameworks/Python.framework/Versions/2.7/bin',
'/Library/Frameworks/Python.framework/Versions/2.7/bin',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload',
'/Library/Python/2.7/site-packages',
'/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/IPython/extensions',
'/Users/lewislevin/.ipython']

Seems ok. Looks like you can't run pyside_postinstall twice.

Wish this stuff wasn't so fragile. I am sure you tend to think of QT and PySide as development tools/libraries, but for many users it is a RUNTIME for pre-existing code. So, there has to be some reasonable way to install and uninstall it.
