[Numpy-discussion] Problem installing numpy on Gentoo

I am trying to install numpy on Gentoo (see my info below for version
etc).  It all seems to go fine, but when I try to import it and run
the tests, I get the following error (in ipython):

In [1]: import numpy
import linalg -> failed: libg2c.so.0: cannot open shared object file:
No such file or directory

I have gfortran on my system, but libg2c is not part of the gcc-4.1.1
distribution anymore (maybe that is a bug with Gentoo?).  I also get
the same error when I run f2py from the command line.

Here is the bug I filed: http://bugs.gentoo.org/show_bug.cgi?id=136988

Info that might help:
