Comment (by kencu):

 I did notice something strange when I reinstalled grace with +universal.
 It of course went back and rebuilt all the deps universal as well, and
 during that process, it pulled in the current m4 port. I'm not sure what
 triggered that requirement, but given what is happening to you, perhaps it
 is relevant to your issue.
 {{{
 $ port -v installed m4
 The following ports are currently installed:
   m4 @1.4.18_1+universal (active) platform='darwin 10' archs='i386 x86_64'
 date='2017-03-26T12:14:02-0700'
 }}}

 So I'd say give `sudo port -v install grace +universal` a try, and see
 what happens. You don't have much (anything) to lose doing so.
