Maybe not an issue here, but the above is a problem I don’t personally see so you should look into it...

right, the above is what I expected.

I can reproduce here on my 10.13 machine using the binary tarballs, and in fact if I look at the build logs for those tarballs

https://build.macports.org/builders/ports-10.13_x86_64-builder/builds/124766/steps/install-port/logs/stdio/text <https://build.macports.org/builders/ports-10.13_x86_64-builder/builds/124766/steps/install-port/logs/stdio/text>

you can see the build was indeed configured to use macports clang-11, which is why its needed at runtime with rustc. 

If though I start a new build by hand, it doesn’t use macports clang 11 and instead uses Xcode clang (the norm on  ’newer’ systems).

I don’t know why, but it seems then there is a mis-match between what the port now thinks it needs, and what was used for the last binary tarball. I’ll commit a rev-bump just to trigger a rebuild and hopefully that will fix things.

In the meantime if you are in a hurry installing macports clang 11 should also fix things.
