I've just installed portmaster for testing - you're right, it does not
show up as depending on ruby; vim, however, does:
# pkg info -r ruby
Interesting thing: portmaster's Makefile does not mention ruby at all.
So I tried something: I removed ruby and vim and portmaster, then
installed portmaster again - and no ruby. So my guess is: portmaster
does no longer depend on ruby.
I'll now be installing vim again, and notice version changes:
Additionally, pkg and perl get upgraded, too. I have to say, pkg is
really great. :-)

Depending on the services your server runs, it should have been possible
to construct something like
# pkg info -r ruby | something | something else | xargs -n 1 service stop
to stop the services that depend on ruby before performing the upgrade.
As others have mentioned, tools like lsof and a "non-deleting pkg delete"
would also provide information on where ruby is in use.
