Rust does not build on an OS X version as old as you are using.
Software developers frequently remove support for older operating systems from
their projects, on the assumption that nobody is using those older OS versions
anymore, or more frequently, they simply make changes to their code which
breaks older systems, unbeknownst to them because they don't test on systems
that old anymore. If you contact them about this, then that will let them know
that it is broken on older systems and that there are still users of such
systems who would like to use their software. If enough users do this, maybe
the developers will reconsider their project's minimum supported OS version
and/or fix whatever problem is preventing the build on older systems. If you
can help them identify and fix whatever it is, that will make it even easier
for them to put the change into their code, which will then eventually make its
way back into MacPorts.
