Your ports tree seems to be out of date. The current version would be
openmpi @1.4.2. This older version does not have a +gcc44 variant yet,
so it falls back to the default.

To switch to gcc44:
sudo port selfupdate
sudo port upgrade outdated
sudo port upgrade --enforce-variants openmpi -gcc43 +gcc44

openmpi installs /opt/local/bin/openmpicc, you are probably executing
/usr/bin/mpicc here.
