As I wrote in the ticket I'm not exactly sure what you're using a
virtualenv for.
To be clear, I think it's great to use virtualenv for development in
general. But I think this will only confuse things when building
SAGE-THE-DISTRIBUTION from scratch since everything should get
installed into $SAGE_LOCAL.
So I'm not sure what you're doing with a virtualenv or why.
