Livecheck is used by developers who want to know if a new version of software exists upstream; since we are the upstream providers of the MacPorts software, we already know when new versions are released; we don't need to use livecheck on this port. We could just turn livecheck off. But for now I've fixed the livecheck to skip non-stable versions:

OK. Guess I'll have to learn to ask what I want, not what I think ...

I have several macs with a normal MacPorts installation with lots of ports running fine, with daily port selfupdate, port upgrade outdated, and more.

For munin I created a second MacPorts environment, without selfupdate etc, because while working on a specific item, I don't want to be disturbed by changes in MacPorts version of changed ports I depend on. But I do want to know when that happens. The other day there it took 2 days to build munin on the other macs and there was not much fun in the differences (like 2.5.0 released, and some subtle changes in ports).

As port livecheck works fine for normal ports, and did work fine for port livecheck macports, until 2.5.0, I used that.

Q: I'm looking for a [bash] procedure to check if MacPorts has changed *without* doing the selfupdate. Can you make a suggestion?
