In particular, if a port breaks on 6.1 but works on 6.2, it is likely
that a POLA violation is afoot somewhere.  This doesn't mean that the
issue will be fixed but instead that something of this sort is unlikely.
Unlike in other operating systems, FreeBSD is incredibly consistent between
minor version numbers.  Usually this means things just work.

e.g., throughout the life of 4.x I rarely encountered problems because of
mixing PORTS and an older release of 4.x.  And by rarely I mean I don't
remember any examples of it happening.
