doh! Yet another obvious answer that escaped me, thanks. It is worth
noting however, that this only applies to FreeBSD I don't see anything
like it in OpenBSD. Free has a more comprehensive ports collection
than Open though, so that's not a huge surprise. I don't have a
NetBSD box to check for comparison.
Despite me being blind, I think my other comment still holds true.
