 {{{/Applications/MacPorts/X11.app/Contents/MacOS/}}} can be run, it's just
 when I open the app bundle the system complains it needs 11.2 while I have
 11.1. Similarly for {{{/opt/local/libexec/llvm-11/bin/clang}}} it can be
 run in terminal but {{{xcrun}}} seems to have problems with it.

 I suspect that is just not the same checks are performed running a binary
 at the command line to through xcrun, or as a system application, and its
 something to do with the above. I've submitted a rebuild for all the llvm
 11 ports so lets see if that helps.
