Changes (by jmroot):

 * port:  ghc => ghc alex


Comment:

 This is because alex, like every port that includes the haskell_stack
 portgroup, sets `supported_archs     x86_64`. If alex's architecture
 doesn't matter to ghc, use `depends_skip_archcheck`. Or if alex only
 installs an executable, it could set `installs_libs no`.
