Comment (by ryandesign):

 Well the first error in the fail log is:

 {{{
 cargo:warning=In file included from
 /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/ncurses.h:141:
 cargo:warning=/opt/local/include/unctrl.h:61:63: error: unknown type name
 'SCREEN'
 }}}

 This shows you're using macOS ncurses.h but MacPorts unctrl.h. These are
 both headers that belong to the ncurses software but macOS and MacPorts
 provide different versions of that software so the headers are apparently
 not interchangeable. Either use all macOS ncurses headers and libraries or
 (ideally) use all MacPorts ncurses headers and libraries.
