While upgrading octave to version 8.4.0 the buildbots ran into the following issue:

Note: I did not see this error on my local builds (sundials5 with mpich-default @4.1.1_0+gcc12, under Ventura arm64 and x86_64)

The mirror step evaluates all available variants. You will see the issue locally if you use the particular variant that adds the nonexistent dependency.

I would assume this must be a problem with the mpi portgroup. Some other ports are getting the bad dependency by default, for example OpenCoarrays.

In 05ea017f71a57fb7162588a89a71066a69170bfa/macports-ports (master):

mpich, openmpi: add gcc13 and clang17 variants

I also globally allows clang15+ since it was fixed on 10.5+

Closes: #68653

Oh yeah, now I remember we've had this problem before. It probably needs to be documented that updating the compilers portgroup with new versions requires either adding the support to the mpis as well, or doing something like this: ​https://github.com/macports/macports-ports/commit/21ddd619cd3c7e42bbc2c288d06c8240cb54e025
