"pip install PySide" fails from local Python installs

[austinmatherne]

I've used pythonbrew, pythonz, and pyenv to install CPython 3.3.1, but all of them give me the same error when running "pip install PySide":

error: Failed to locate the Python library /home/.../lib/libpython3.3m.so

Is this a problem with PySide, or with the various local Python installers I've used?

If I use the system version of pip, PySide installs just fine.
