[Mesa-users] STELLA compilation failed on MacOS Tahoe (M3)

[Philip Mocz]

Looking into this, it looks like the new colors module is not linked up to
stella, and the stella_extras.f90 file is using the old module's interface.

For now you'll need to use the previous Mesa version until the
stellar_extras.f90 file is updated to link to the new colors module and
this gets patched in the next release version
