[AstroPy] error building astropy on Lion

[Jean-Claude Passy]

Hi,

I am new on the mailing list and would like to try the astropy package. 
Unfortunately, I cannot get it installed with the pip command (see error 
below).
I have installed a full version of Python 2.7.2 through the yT package. 
I am running on Mac OS Lion.

I would really appreciate if someone could help me fix this.
Thanks a lot,

JC
