gmp is available as R package http://cran.r-project.org/web/packages/gmp/index.html do you really need it at a lower level than that? > I have installed mpfr and gmp > under the instructions of the following website > http://pauillac.inria.fr/cdrom_a_graver/prog/pc/mpfr/eng.htm and I get > no errors.

That bears no meaning - as you said you installed the libraries, so you have to use those. Source code of gmp/mpfr has no effect on your code and should not be anywhere near it.
