This PHP script lives on my server and the molden and dcraw portfiles use it as their livecheck. For pspp-devel we want three values -- version, snapshot date, and hash. I've now updated that script to return this information about pspp-devel as well.

I understand the utility of having all three pieces of information combined (and it already exists on the original site that way), but I would rather not have to do daily investigations of the port due to the build number. I'd like to find a better solution.

Oh I see. They keep doing new builds of the same source version, and then sometimes they update to a new source version with a new hash. Well, that's all very strange of them. And the problem is that even when they're building the same source version, they've created a new tarball of it which has different checksums. Hence your latest update to pspp-devel now causes a checksum mismatch for anyone who had the old file downloaded:

$ sudo port install pspp-devel

Also, your update increased the revision, but also changed the version to an "earlier" one as far as MacPorts is concerned ("0.7.5" is less than "0.7.5-g551ae7"):

$ port installed pspp-devel
The following ports are currently installed:
  pspp-devel @0.7.5-g551ae7_2+universal (active)
$ port outdated pspp-devel
No installed ports are outdated.
$ port -v outdated pspp-devel
The following installed ports are outdated:
pspp-devel                     0.7.5-g551ae7_2 > 0.7.5_3  !

> MacPorts doesn't seem to have a way to handle a simple "if different" livecheck -- it only wants to deal with finding the newest version. I'm going to work on a patch that adds that adds this feature, simply checking if the strings are different, regardless of order. I feel it would be much better suited to the needs of this port and possibly other -devels.

The md5 livecheck type seems to handle that adequately. Though I've never found a reason to prefer that kind of check.

The livecheck you've got in the port now should work too -- it tells you if the version upstream is different from the version in the portfile, regardless of which one it thinks is newer.
