This is a local configuration issue, not really an Open MPI issue.

Open MPI will compile itself with whichever compiler you tell it to; if you have both gcc 4.3 and 4.6 installed correctly on your machine, you can probably configure Open MPI with:

./configure CC=/path/to/gcc4.3/bin/gcc CXX=/path/to/gcc4.3/bin/g++ \
   F77=/path/to/gcc4.3/bin/gfortran FC=/path/to/gcc4.3/bin/gfortran ...

Make sense?
