The log looks rather weird. You're using Py2.7 and try to install it with
setuptools in a virtualenv. And the log shows lots of recursion within
distutils and setuptools.

Can you pass the "--distribute" option to virtualenv, to see if it's a
setuptools bug? That replaces setuptools by the known-to-be-way-better
distribute package. You should be using that anyway, setuptools is no
longer maintained.

I meant to create the virtualenv with distribute installed instead of
setuptools, i.e.

virtualenv --distribute myvenv
