I think that the gcc maintainer will probably switch the default
Fortran compiler to gcc46 after gcc46 has been tested a bit longer,
and some of the remaining bugs fixed.  You could of course switch the
default on your own machines.  AVX support requires more than just a
new compiler and the proper hardware: at the moment, FreeBSD doesn't
support AVX, although some outside developers expressed an interest in
adding support for it:

but this will probably take some time.
