--------------------------+-------------------------------
 Something very recently has broken `OpenBLAS` finding with clang builds
 for some port(s). See: https://github.com/macports/macports-
 ports/pull/20901

 I tried to upgrade `madness`, which worked fine locally for me and worked
 on every system earlier for months:
 https://ports.macports.org/port/madness/details (well, okay, 10.6 Intel
 failed, it seems).
 Upgrade failed with:

 Initially I attributed that to a recent commit to upstream:
 https://github.com/m-a-d-n-e-s-s/madness/issues/504

 However, when I tried revbumping our existing version of `madness`, it
 failed identically. It also fails now on Sonoma for me locally. Building
 with GCC on 10.6 PowerPC works fine.

 I have no idea what goes wrong. Could someone help here?
