 success:

 It's a little weird, in that the dylibs for each arch have different
 names:
 {{{

 }}}

 but perhaps that is how rust works. The binaries are fat:
 {{{
 % file /opt/local/bin/rustc
 /opt/local/bin/rustc: Mach-O universal binary with 2 architectures:
 [x86_64:Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable
 arm64]
 /opt/local/bin/rustc (for architecture x86_64): Mach-O 64-bit executable
 x86_64
 /opt/local/bin/rustc (for architecture arm64):  Mach-O 64-bit executable
 arm64
 }}}

 we'll see how it works. I'll put up a PR for the minor rust changes.
