[R] ATLAS

Dear R-users,

I want to install R on our new Red Hat machine and I want R to use ATLAS for
its linear algebra calculations. The R-admin manual recommends building
ATLAS into a shared BLAS library, which means that R should be able of
detecting the library at RUN-TIME and fall back if there is none.

I remember there was a discussion how to make R use BLAS, but that seems to
deal with static linking only. Actually the very existence of that
discussion made me doubt about the things that are probably obvious. So here
are my questions:

* Do I need to make any modifications to the configure in order to build R
that can dynamically link with BLAS shared library? If not, than the
precompiled binary distribution should be able of doing this as well, right?
* I assume that the order of building BLAS and R does not matter (as opposed
to the static linking case).
* How do I tell that R successfully finds the BLAS shared library?

Thanks,
Vadim
