[R] Installing Rmpi on FC5 with lam

[Thomas Mangold]

After several trial and error attempts, I managed to install the Rmpi 
package without error on my Linux machine, running Fedora 5.
I installed lam-7.1.2, lam-devel-7.1.2 and R-2.4.1, R-devel-2.4.1
The Package Rmpi_5.0-3.tar.gz, I installed once from within R and once 
from the command line to make sure, I link the right libraries:
R CMD INSTALL Rmpi_5.0-3.tar.gz --configure-args="--with-mpi=/usr/lib/lam"

Rmpi is correctly installed in $R_HOME/library/Rmpi.
However on compiling, I get strange warnings:

internal.c: In function ‘mystrcpy’:
internal.c:64: warning: operation on ‘i’ may be undefined
internal.c: In function ‘mpitype’:
internal.c:43: warning: ‘datatype’ may be used uninitialized in this

On loading the library occurs the following error:
 > library(Rmpi)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library '/usr/lib/R/library/Rmpi/libs/Rmpi.so':
/usr/lib/R/library/Rmpi/libs/Rmpi.so: undefined symbol: lam_mpi_double
Error in library(Rmpi) : .First.lib failed for 'Rmpi'
Error in dyn.unload(x) : dynamic/shared library 
'/usr/lib/R/library/Rmpi/libs/Rmpi.so' was not loaded

I'm running kernel 2.6.18-1.2257.fc5smp on a i686 machine

Thank you for any ideas.
