   This makes me cautiously optimistic.

   The idea would be that pkgsrc defines its supported rust version, 
and it's up to the user to make sure that version is installed (or 
builds will simply fail when it tries to run the rust commands).  Just 
to be clear, installing a specific version is extremely easy, and just 
requires running a single command (assuming one has rustup installed 
already):

   $ rustup install 1.67.0

   In this hypothetical world, there would be a pkgsrc command to show 
the current required rust version:

   $ make show-var VARNAME=RUST_VERSION
   1.67.0

   .. allowing people to script automatic installation of required 
toolchain versions.

   Again, cautiously optimistic.  :)
