Comment (by ghleclerc@…):

 I did some poking around.  Turns out that in the 1.8 release of Rust,
 which Macports fetches, the compiler version check in the configure script
 of Rust has this line in it :

 (7.0* | 7.1* | 7.2*)

 which will not work with the latest XCode (7.3.1) since clang reports
 version 7.3... for this XCode version.

 I have looked at the source in the rust 1.9 release and it is fixed to

 (7.0* | 7.1* | 7.2* | 7.3*)

 which does work.  I have manually patched my version in Macports and
 successfully compiled version 1.8.

 I don't know what is the plan for the Rust port.  Probably updating the
 port to 1.9 will fix the problem and that might be simpler than patching
 the 1.8 version.  I just don't know enough about Macports system to create
 the patch.  It is simple enough (one line (1034) in the configure script),
 but might still be more complicated than updating the version.

 Hope this helps.
