 The compilers portgroup can print this message:

 {{{
 must set at least one Fortran variant (e.g. +gfortran, +gccX, +g95)
 }}}

 But it prints this message even if the port in question doesn't offer all
 of those variants, leading to user confusion.

 For example, here, upon seeing this message, the user tried installing the
 port with +gfortran, only to see the message again, because the port
 didn't actually provide a gfortran variant:
