I uninstalled gcc46 and install gcc45 +gfortran.

> Where did /opt/local/bin/gfortran come from? gcc46 +gfortran should (hopefully -- I haven't tried it) only install /opt/local/bin/gfortran-mp-4.6. Try "port provides /opt/local/bin/gfortran"; if it says gcc46 provided it, file a bug report against the gcc46 port.

Yes it install as /opt/local/bin/gfortran-mp-4.6

I moved aside, /usr/local, and used gcc45.  eigen3 appears to have
installed.  Thanks for your help.
