Comment (by Schamschula):

 I'm going to have to look into this.

 The build bot had a clean build (for the non-universal version) yesterday,
 before I updated the Portfile to deal with macOS  versions that entirely
 fail to build {{{xar 1.8.0.501}}}.

 I need to check if El Capitan gets the correct patch file for
 {{{src/xar_internal.h}}}.
