Comment (by mascguy):

 Replying to [comment:8 neverpanic]:
 > I'm guessing that bootstrap binary would have to be compiled on 10.8 or
 lower? I don't have a machine this old anymore, so I can't do that,
 unfortunately.

 > It may be as simple also also changing openssl.branch in the rust-
 bootstrap Portfile, but building that requires jemalloc +universal, which
 doesn't seem to compile on my 12.4 arm64. If I build it -universal, that
 seems to work fine, though.

 I have VMs covering every macOS release from 10.6 through Monterey, so I
 can test that change on 10.6 through 10.8.

 More to follow, once that's done.

 Marcus, if you're available to respond... any thoughts/concerns?
