  error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/test-easy-install-1712.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /Library/Python/2.7/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

Please make the appropriate changes for your system and try again.

I am running Python 2.7.3 and have no packages installed except what comes by default, pip and virtualenv on OSX Mountain Lion.

Whoops, forgot to write my answer to this question.

My Python directory had a whole bunch of permission and package related problems; ended up doing a complete uninstall then installed the latest one from Python.org.

Been working fine ever since.

Your Python installation is somehow messed up.

First, running sudo virtualenv foo doesn't make any sense. The whole point of virtualenv is so that you don't ever need root access to install packages. You will never need sudo to use virtualenv.

Second, /Library/Python/2.7/site-packages/virtualenv.py is not included by default with Mountain Lion. Something has installed it there, so you are mistaken when you say you "have no packages installed except what comes by default". Depending on how you got that installed, it may be installed wrong.

It appears that even though you are creating a virtualenv, it's trying to install packages into /Library/Python/2.7/site-packages/, which shouldn't be possible. Could it be that you used sudo easy_install to install virtualenv, or manually put some packages in /Library/Python/2.7/site-packages/?

I would suggest un-doing and un-installing whatever you installed, getting your system back to standard Mac OS X set-up, and then using virtualenv-burrito instead, it is a one-step command that will install virtualenv and pip for you with no thinking required: https://github.com/brainsik/virtualenv-burrito
