Hi Tom,

Yes, a similar error has been reported with virtualenv 1.8.3,
see https://github.com/pypa/virtualenv/issues/359

If you were not aware, the TravisCI team are currently actively
trying to get NumPy preinstalled on the virtual machines. As I
write this, Python 2.5, 2.6 and 2.7 now have NumPy while
Python 3.1 is being dropped (it was only ever an unofficially
supported platform), and NumPy under Python 3.2 and 3.3
is still in progress. See:


This "ValueError: underlying buffer has been detached" was
one of the issues the TravisCI team had faced.
