Short answer to your questsion (from the 'Subject') is : NO !
For an example, see below:

In some configurations, R does not need *any* shared libraries,
and there, $R_HOME/lib does *not* exist.
E.g., I have one of my R-devel versions installed (on Fedora
Linux) with
../R/configure --with-blas=-lflexiblas
using the nice, currently Fedora/Redhat-only "flexiblas"
approach, with which I can nicely switch the versions of BLAS
and Lapack libraries that R works with from within R.
As that version of R is not "shared", i.e., no libR.so , *and*
gets both its BLAS and Lapack libraries from "external" (not
from R), there's no need for a ./lib/ and so none is created.
