Yes, those are broken currently.

I think we can insert that as a last fallback: build from the
last-rel version (which should be 5.8.6).
I'll have a look at it tomorrow.

On your own systems (xdarwin) you could easily inject a working pair
of cm3/cm3cg into the last-ok pool, that should fix mismatches.
