This changed when the newer Fortran compiler and newer Atlas/Lapack were
used. You can see for yourself:
$ R CMD config BLAS_LIBS
-lblas
$ R CMD config LAPACK_LIBS
-llapack
Not -lRlapack but -llapack. FWIW my system (at work) is Ubuntu 8.10:
$ dpkg -l r-base-core

I maintain RPy2 in Debian, if you know the tricks you can just fetch the
source package from there and rebuild it on your Ubuntu system. I do that
with a few things that I want to be even more current than the Ubuntu cycle
(and the excellent contributed/ported R packages via CRAN).
Otherwise, just edit setup.py and try again.
