Hmm..but previously if you had libgtkhtml-2.2.3 installed (i.e. the
same version) this would also have failed.

The major benefit of this change is that it prevents people from
installing one copy of the port over an older version, thereby
screwing up their /var/db/pkg and possibly leaving orphan files lying
around.  I think that is important enough that it should stay in, in
some form.

In your case since the PREFIX is different they don't actually
conflict so one might argue that it should be allowed.  I suppose
that's something that could be checked in bsd.port.mk by extracting
the prefix for the existing package from the contents file and
comparing to PREFIX.
