There are several way about it.

The first would be to actually use one of Debian's packages -- unstable currently uses gcc 4.0.1 / g77 3.4.*. That seems to work well. You'd get the same released version for amd64 as well. I'd do that.

The second would be to continue building on your own, but to make sure the generated Makeconf (which the Debian package copies into /etc/R/) has the right settings.

Hope this helps, Dirk
