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.
