#57169: clang-3.9 @ 3.91 -universal: fails to compile on MacOS X 10.14 (Mojave)
--------------------------+-----------------------
 Reporter:  andreavicere  |      Owner:  (none)
     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.5.3
 Keywords:  mojave        |       Port:  clang-3.9
--------------------------+-----------------------
 The compilation of clang-3.9 on Mojave fails with error:

 {{{
 sudo port install clang-3.9 -universal
 --->  Computing dependencies for clang-3.9
 --->  Fetching distfiles for clang-3.9
 Error: clang-3.9 is not supported on macOS Mojave or newer.
 Error: Failed to fetch clang-3.9: unsupported platform
 }}}

 Mojave is explicitly excluded in the port [https://github.com/macports
 /macports-ports/blob/master/lang/llvm-3.9/Portfile source], even choosing
 the {{{-universal}}} variant to restrict compilation to the x64
 architecture.
 The dependency {{{llvm-3.9}}} instead compiles fine with the
 {{{-universal}}} switch.

 If the error implies that clang-3.9 is slated not to be ported to Mojave,
 it might be worth recommending in the error message to switch to a
 different version?
