[igraph] Install to virtualenv on OSX 10.8 failing

[Adam Tebbe]

I'm trying to install python-igraph into a virtualenv on OSX 10.8.2.  I 
installed igraph using homebrew and have tried installing python-igraph using 
pip and easy_install.  Both fail with the following.  Any tips on how to get 
this to compile?

(virtualenv)mymachine:virtualenv adam$ easy_install python-igraph
