What have I forgotten about specifying which Perl should be /opt/local/bin/perl?

The latter, since the former, although possibly more useful, is too difficult.

Ideally, one has active the latest available version of a port, esp. given dependencies. But that doesn't always build, nor even always fail on first use after being built. Some might wish to let stuff age a bit for stability's sake, but not excessively, and dates might help with that.

A possible alternative: a reasonably easy way to keep only the most recent X inactive versions of a port with a given set of variants. That way one could keep things reasonably clean but have something to fall back to. If there's a non-manual way to do that (short of a creative script that digests the output of "port installed"), I must have missed it.
