I've never liked this step much, especially since by definition you
should only be building installed ports during migration. But it is
theoretically possible that someone has a half-finished build for a port
they don't have installed but is a dependency of something else on the
new platform only.

'sudo rm -rf /opt/local/var/macports/build/*' would do the trick but
apparently that wasn't "nice" enough.

This actually isn't a problem at all. We can't install old versions, so
what you end up with is the current version of each port, with the
previously active variants (if any) active, and any other listed variant
combinations inactive.
