Hi Simon,

Make check passed all tests. (Easy peasy hey ;-)

The problem I now have, is when I try running any of the examples or usrp
.py scripts I get "ImportError: No module named gnuradio".

How do I get python to find the gnuradio module?

There are two ways to go about this in Gentoo. The main problem is that python in Gentoo's portage installs/looks for modules in /usr/ whereas other distributions and GNU Radio install and look in /usr/local by default.

The first solution is to add a path to your python environment to point to the newly installed python modules in /usr/local/<something>.

The second method, which I found is much easier and helps stay consistent when I used to run Gentoo, is to change the prefix on configure:
./configure --prefix=/usr/

I think you're on this track as you specified --exec-prefix... just also specify a --prefix.
