R_HOME is not the issue, and I believe that R_LIBS is not involved with
packages such as "datasets", "utils", etc...
I suspect that the issue is around dynamic loading of C libraries, as
depending on the way the R shared library is called the issue is absent or
present, but the error reporting from R makes tracking this easy.
