Comment (by Wowfunhappy):

 > The error message comes from MacPorts base, not the portfile. What
 wording would you find clearer?

 Something like "gcc7 cannot be built universal for ppc and i386." :)

 The current error message led me to try installing gmp as +universal. When
 that worked, I got very confused.
