One approach that could also work would be to have installmisc.sh do the
following:

PYTHON_SITELIB=`python -c "from distutils.sysconfig import
get_python_lib; print(get_python_lib())"`

PYTHON_SITEARCH=`python -c "from distutils.sysconfig import
get_python_lib; print(get_python_lib(1))"`

And then pass sys.path.insert(0, "$PYTHON_SITELIB:%PYTHON_SITEARCH")

(This is similar to how it's done in spec files for Red Hat and Fedora)

This is also very portable, since we're asking python itself what path
it's expecting to need.
