src_prepare() { sed -e "s:nosetests :nosetests-${EPYTHON} :" \ -i tests/Makefile || die } Folks, what the...?! Plus it's completely unnecessary. python-single-r1_pkg_setup() ensures that the environment is set up properly to use the proper variant of nose.
I've just tested it with python3.3 set as global interp and it works fine without the sed. Committed.
