Comment (by TheLastLovemark):

 **It worked for me without the +debug variant.**

 This is not the only ticket I have open regarding a port failing to build
 with the debug variant.

 Any idea why the install seems to work only without the +debug variant?

 I'm on High Sierra and can not upgrade any further (Mid 2010 MBP).
