A quick perusal of the Portfiles verifies your statement, thanks for
clarifying.  However, I've installed gcc43, 44, 45, and 46 all with the
+gfortran variant (of which only gcc46 needs it) and it's always worked as
expected.  Perhaps port quietly ignores any specified, non-existent
variants?

I keep my definitions updated (religiously), and have actually rid myself of
the need to use "sudo" by changing permissions of /Applications/MacPorts and
/opt, (I like to reserve the necessity of using root privileges for mucking
about in /usr, /bin, /include, etc.; not /usr/local or /opt or any other
place I choose to install compiled software)

All the best,
Jason
