I'm not sure
I build like following on Ubuntu 9.10 amd64.

$ tar xvfz GotoBLAS2-1.13.tar.gz
$ cd GotoBLAS2
$ ./quickbuild.64bit
ln -fs libgoto2_nehalemp-r1.13.a libgoto2.a
for d in interface driver/level2 driver/level3 driver/others kernel  lapack ; \
        do if test -d $d; then \
          make -j 8 -C $d libs || exit 1 ; \
        fi; \
        done
