Hey Team Astropy,

I'm having some issues installing astropy from pip (where it seems like
there's some SSL certificate problem) that I'm not sure how to fix.

I'm running Mountain Lion (OS X) and python version 2.7.3:

>>> import sys
>>> print sys.version
2.7.3 |EPD 7.3-1 (32-bit)| (default, Apr 12 2012, 11:28:34)
[GCC 4.0.1 (Apple Inc. build 5493)]


When I do:

[longtrail:~] dnarayanan% pip install astropy

I get:

Downloading/unpacking astropy

problem confirming the ssl certificate: <urlopen error [Errno 1]
