I am afraid I cannot, moreover, for some reason, from a non root account I
get:

giannerini_at_gauss:~> su
[...]
gauss:/home/giannerini # cd /root/Desktop/
gauss:~/Desktop # CC="mpicc" R CMD INSTALL Rmpi_0.5-5.tar.gz
--configure-args=--with-mpi=/usr/lib64/mpi/gcc/openmpi/
* Installing to library '/usr/local/lib64/R/library'
* Installing *source* package 'Rmpi' ...
checking for gcc... mpicc
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run C
compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
ERROR: configuration failed for package 'Rmpi'
** Removing '/usr/local/lib64/R/library/Rmpi'
** Restoring previous '/usr/local/lib64/R/library/Rmpi'

gauss:~/Desktop # R CMD INSTALL Rmpi_0.5-5.tar.gz
--configure-args=--with-mpi=/usr/lib64/mpi/gcc/openmpi/
* Installing to library '/usr/local/lib64/R/library'
[...]
** building package indices ...
* DONE (Rmpi)

Notice that now it works only if I remove the CC directive. In any case I
confirm that I can load the package Rmpi even if I am experiencing some
problems, will study a bit and in case get back to the forum, thanks again.
