At first glance it looks like pkg_which can be replaced with
'pkg_info -W' (the grep stuff may have to be changed, I haven't looked
into it) and the portupgrade piece can be replaced with the
equivalent in portmaster. There could be an
upgrade-site-packages-portmaster target or the equivalent instructions
can be added to UPDATING.

# Major upgrade support
PORTUPGRADE_CMD?=       ${LOCALBASE}/sbin/portupgrade
PKG_WHICH_CMD?= ${LOCALBASE}/sbin/pkg_which
upgrade-site-packages:
        @if [ ! -x ${PORTUPGRADE_CMD} ]; then \
                ${ECHO_MSG} "Please install ports-mgmt/portupgrade."; \
                ${FALSE}; \
         fi

        @for ver in `echo ${_PYTHON_ALLBRANCHES}|${SED} 's/${PYTHON_VER}//'`; do \
                if [ -d ${PREFIX}/lib/python$$ver ]; then \
                        UPD=`${FIND} ${PREFIX}/lib/python$$ver \
