Ports in MacPorts shouldn't be using any extra compilers you may have installed (except for a few select ports that explicitly request to do so). Or did you "gcc_select" it by any chance? Some ports will then mistakenly use the compiler you gcc_selected instead of the default compiler.

Have you tried running these ports' test suite?

sudo port -d test gmp

sudo port -d test mpfr

Do the test suites pass?
