I have a new feature in the svn version of portmaster called
--packages-build that for any given run creates an internal list of
dependencies that are only ever listed as build deps (never run deps)
and installs packages for them but builds everything else. This
feature was created at the request of one of companies that sponsored
the package installation code. Currently it does not pkg_delete those
packages when it's done, but I could easily add that.

Actually I suppose it would not be too hard to extend that "list of
build only deps" idea to a general feature which deletes them when
done. Something like --delete-build-only maybe? This would be limited
to the subset of the list of build-only deps that portmaster actually
installed. Just because something is build-only for a given run of
portmaster doesn't mean that it isn't a run dep for something else if
it is already installed.

Well then don't use the option. :)  Options are generally good things.
