A lot of your testsuite failures are scipy/numpy related. The above failure
seems to be from building against the python:3.2 slot. I'm not sure this can be
done? To build scipy against just the python:2.7 slot (this is needed by sog)
do 

USE_PYTHON="2.7" emerge scipy

Hopefully this will get you rolling.
