work-around for Xcode 15 linker issue?

[Murray Eisenberg]

Several ports I had been trying tore-ininstall under macOS Sonoma (in order to re-install, finally, maxima and wxMaxima,
still seem to be failing configuration, even though I did add the two exports to my ~/.profile (and, of course, after restarting the shell), namely:

ipopt, sbcl, scalapack, scotch

I've updated existiing, or filed new, tickets about that.

Anything else to try?
