my guess is the fix in #12134 was fragile, and the version should be picked in a more robust way /cc @euantorano

I'd guess this is due to freebsd/latest now being OpenBSD 6.9 rather than 6.8, and picking up a newer version of boehm.

[euantorano]

Yep, in OpenBSD 6.9 it's now libgc.so.5.0. That would definitely cause this breakage.
