Comment (by david@…):

 Just build ruby from source (outside Macports).

 Ruby builds + tests good.

 Installation of wpscan worked first time.

 No problems reported building ffi, so it appears something is a bit off in
 the Portfile.

 And I see no major differences between the two Portfiles for ruby22 (which
 works) + ruby23 (which fails).
