-L/usr/lib64 I think. I have
#LAPACK_LIBS="-L/usr/lib64 -llapack"
(commented out now) in config.site.
../R/configure --with-lapack="-L/usr/lib64 -llapack"
seems to work with FC4/Opteron (even with the configure line, you
still need to have at least "--with-lapack" on the command line, which
is a bit of a bug -- or will be one, once we stop advising against
using external lapack libs in the first place...).
A line like
External libraries: readline, BLAS(ATLAS), LAPACK(generic)
shows that R is not using the internal versions of BLAS/LAPACK. (Of
course, the ATLAS bit required more work...)
The latest updates to lapack seem not to have worked.
