Comment (by rmottola):

 Happens on 10.11 El Capitan too.

 I tried using gcc12 I have installed, but fail:


 {{{
 --->  Computing dependencies for libomp...
 Error: Cannot install libgcc13 for the archs 'i386 x86_64' because
 Error: its dependency libmpc cannot build for the required archs.
 }}}

 I suppose this is not a libomp issue, but a libgcc13 issue now?

 clang 6.0 worked. Is that already a dependency issue?
 system clang is 8.0 here... so somehow strange.
