Yep the admin thing did it, successfully installed gf2x. Don't know why I 
wasn't running cygwin as admin the entire time....

But now I got an error on Pillows which I understand to be an image 
manipulation liubrary for python:

Error building / installing Pillow

I tried to install the tarball attached 
here<http://trac.sagemath.org/ticket/15539#comment:15> but 
I think that it is the same one distributed with sage.

Also I found a mention of the Pillow install problem here 
<http://trac.sagemath.org/ticket/15317#comment:25>and 
they said that it was an easy fix though I did not follow how the 
suggestion would solve the issue.
