[R] compiling R with tuned BLAS

I am looking at the instructions on
http://cran.r-project.org/doc/manuals/r-patched/R-admin.html#ATLAS
I have noticed that ATLAS produces two shared libs in addition to the
*.a files:
http://math-atlas.sourceforge.net/atlas_install/node22.html
contents of the ATLAS lib directory:
libatlas.a libcblas.a libf77blas.a liblapack.a libptcblas.a
libptf77blas.a libsatlas.so libtatlas.so
The instructions do not appear to match up with the *.a files & *.so
files as described. (it appears to want me to use shared libs, but the
names defined are static libs, not shared libs).
should I simply be having it link against libtatlas.so (and pthreads)
for shared threaded atlas and libsatlas.so for shared sequential atlas?
do I need shared versions of the other static libraries?
I think the help is a bit out of date, or at least unclear as to what it
intends of me.
