You probably need to rebuild everything that linked with libgfortran.so.1, AFAIK, in gcc 4.3 it's libgfortran.so.3.
Could you clarify that suggestion? I tried rebuilding gcc (with the fortran useflag), and then rebuilding octave, but got the exact same error.
I was talking about revdep-rebuild. Looking at your error, it's probably blas, that needs rebuild, but probably more.
Please report back if the Problem is still valid after fixing the libgfortran things of blas and friends.
I rebuilt gcc, blas-atlas, blas-lapack, and openmpi.

I think is this something to fix from the maintainers. Please provide emerge -vp sci-mathematics/octave
This is not octave's fault I think because octave doesn't know and care about MPI and this must hence come from some of the libraries it links against. Please try rebuilding all packages that liboctinterp.so links against, such as hdf5, umfpack and friends, etc. and see if that helps. Thanks, Markus
This should be fixed now in the latest octave 3.2.4. Thanks, Markus
