Sabayon / Gentoo platform

Dear dorsal development team,

I just installed Dolfin with help from dorsal and so I created a
platform file which works for Sabayon Linux and should also work for
Gentoo. I did not test the Gentoo version, since I do not have a pure
Gentoo running, but the Sabayon Linux platform works. So I thought I
share the platform with you. I am not sure if I should open a blueprint for
this, so I attach the platform file here.

# Sabayon Linux 5.x
#
# If you are unfamiliar with mixing portage and equo under Sabayon,
please read:
#
#
http://wiki.sabayon.org/index.php?title=HOWTO:_Safely_mix_Entropy_and_Portage
#
# This build script assumes that you have the following packages
# already installed via Sabayon's equo:
#
# equo install --ask scons bzr libxml2 numpy vtk swig boost \
# gmp cln lapack mpfr
#
# you will also need to emerge these packages on top of the equo command
#
# USE='supernodal mpi metis cxx fortran threads' emerge -av suitesparse \
# scientificpython openmpi
#
# should you get a problem with the UFC when you have python enabled,
export those two paths:
#
# export
PYTHONPATH=${PYTHONPATH}:${HOME}/Work/FEniCS/lib64/python2.6/site-packages
# export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${HOME}/Work/FEniCS/lib
#
# for Gentoo this script should work also, because Sabayon is based on
Gentoo, so one
# should simply emerge all needed packages like:
#
# USE='supernodal mpi metis cxx fortran threads' emerge -av suitesparse \
# scientificpython openmpi scons bzr libxml2 numpy vtk swig boost scons \
# bzr libxml2 numpy vtk swig boost
#
# I did not test the pure gentoo installation yet!
