Can't be imported when installed in a virtualenvwrapper environment

[Singletoned]

I've installed maya on OSX in a virtualenv using virtualenvwrapper with python 2.7 and 3.5. On both of them maya can't be imported even though it's dependencies can (eg humanize) ("ImportError: No module named 'maya'" is reported). I haven't had this problem with any other package in several years of using virtualenvwrapper for all of my environments, so it's quite unusual.

Installing into a manually created virtualenv works fine.

Actually, it turns out installing into a manually created virtualenv also fails, so its not virtualenvwrapper specific.
