My problem

[M. Warner Losh]

I think my problem was caused by a stale ruby18.  When I did a make
delete-old-libs, that program would no longer run due to a missing
library.

Rebuilding it, and then rebuilding portupgrade-devel was the ticket.

You might want to suggest in the UPDATING file that people make sure
their base system is up-to-date, and to update ruby as well after
crossing the gcc 4.2/symbol versioning  rubicon...
