I just talked to Carl. He basically said that for 3.3+ pyenv itself should probably used and that "hopefully virtualenv will die in favor of of pyenv".

Another reason I think that the bootstrap script shouldn't install virtualenv is that of scope. The point of bootstrapping was to make it so pip could be "included" with Python without actually including it. As far as i'm personally concerned it should concern itself with installing pip and setuptools (assuming we can't make setuptools optional in pip or bundled…). We don't need virtualenv to enable ``pip3 install foo`` so it shouldn't be installing it.

Otoh it would be nicer if PyEnv was taken to integrate with pip (although this is possibly a different pip) in that when creating a new environment if pip has already been installed in the "parent" environment it would be copied over into the pyenv created environment.
