For Linux that's correct, but for OS X we are going to put those on PyPi.
Actually, for Numpy those are already there thanks to Matthew's efforts:
https://pypi.python.org/pypi/numpy. For Scipy we plan to do the same for
0.14.0.

Specifically for testing on TravisCI, AstroPy hosts a wheelhouse with Linux
wheels that may be of use:
