Python Import Error for modules installed with Hom

I've already installed PySide using homebrew, but I get an error when my scripts run things such as

from PySide import QtWebKit

When I try brew install pyside I get an error that pyside-1.2.0 already installed

When I try pip install pyside I get the following error:

In file included from /Users/fitvalet/wgwt/env/build/pyside/sources/pyside/plugins/customwidgets.cpp:23:

I also tried easy_install pyside and got this error:

I figured out the problem by reinstalling the homebrew installation of PySide.

When you install using homebrew, you get a warning that

For non-homebrew python (2.x), you need to amend your PYTHONPATH like so:
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

Ran this and the module worked.

To make the change automatic rather than having to type the line each time I opened a new terminal console, I needed to add that line to my ./bash_profile file.
