I checked the environment file and couldn't really figure out where
the various -I include flags were being defined.  In any case, I
noticed that the ebuild compile command that fails is:

i686-pc-freebsd7.2-gcc -pthread -DNDEBUG -O2 -pipe -fPIC
-Ibuild/src.freebsd-7.2-RELEASE-i386-2.6/numpy/core/src
-Inumpy/core/include
-Ibuild/src.freebsd-7.2-RELEASE-i386-2.6/numpy/core/include/numpy
-Inumpy/core/src -Inumpy/core/include
-I/home/michael/gentoo/usr/include/python2.6 -c
build/src.freebsd-7.2-RELEASE-i386-2.6/numpy/core/src/umathmodule.c -o
build/temp.freebsd-7.2-RELEASE-i386-2.6/build/src.freebsd-7.2-RELEASE-i386-2.6/numpy/core/src/umathmodule.o

...adding an additional -Inumpy/core/include/numpy/fenv  (where fenv.h
with the numpy distribution) enables successful compilation, avoiding
pulling in /usr/include/fenv.h

Since I unfortunately lack the effort to dig around in the original
ebuild/numpy/python scripts, I made a single-line change to the
numpy-1.3.0.ebuild file:

        sed -i \
                -e "s:'f77blas':'blas':g" \

which just copies the fenv.h to the numpy/core/include directory so
that -Inumpy/core/include will pick it up.  This is a hack but
whatever, it works in my overlay.  I'm open to better practices and
perhaps a solution that will throw the proper
-Inumpy/core/include/numpy/fenv into the build process.
