Thanks for taking a look at this. I tend to agree with you that it
should be easy to replace. For that matter, it should even be possible
to replace the portupgrade piece with 'make -DFORCE_PKG_REGISTER' but
I certainly wouldn't deny people who use the various maintenance tools
the opportunity to use them.

FWIW, portmaster does the equivalent of 'portupgrade -f' by default,
so the equivalent in the code below would simply be:
${PORTMASTER_CMD} $$UPD;

hope this helps,

Doug
