Hi Shane,

Thanks for your reply.

I have had a look, and there is only 1 version of
setuptools-20.0-py2.7.egg-info in /usr/local/lib/python2.7/site-packages/
So this does not seem to be the issue.

In fact, I think it may be that the setup.py that comes bundled with the
multimedia/quodlibet software does not support
--single-version-externally-managed and therefore requires
PYDISTUTILS_INSTALLNOSINGLE=yes?

Is PYDISTUTILS_INSTALLNOSINGLE being deprecated because each piece of
software that comes bundled with setup.py should be updating it to the
latest which supports --single-version-externally-managed ?

Regards,
Ben
