I now realize my algorithm for reading man portmaster was all wrong. :)
When I started using FreeBSD I decided to not use packages, so I always
disregarded all options dealing with them, and never made the connection
between delete-build-only and local package caching.

I assume this is a typo, it should be 'pm_dbo'?

Skimming through the man page and getopts part of portmaster I don't see
a way to exclude some build-deps from being uninstalled.  Am I missing
something?  I'm not sure ATM, but there could be some of them that are
only ever build dependencies but which I want to keep installed for whatever
reason.

Anyway, thanks a lot for pointing this out, it's a really handy feature!
