Hello,

I am new to Linux and parallel processing, and am having trouble installing Rmpi.  Prior to attempting to install it, I successfully installed lam-MPI (7.1.4) with the shared libraries option instead of static libraries.  I used an Intel Fortran compiler to do it.  (My commands at the terminal were $ ./configure FC=ifort --disable-static --enable-shared,
and then $ make, and finally $sudo make install, and it all seemed to flow fine with no warnings or errors).  BUT when I try to download and install Rmpi while in R and using the install.packages() function in R, I get the following error message (though I have successfully downloaded and installed other packages):

** building package indices ...
** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared library '/home/john/R/i486-pc-linux-gnu-library/2.11/Rmpi/libs/Rmpi.so':
  liblam.so.0: cannot open shared object file: No such file or directory
Warning: .Last.lib failed in detach() for 'Rmpi', details:
  call: dyn.unload(file.path(libpath, "libs", paste("Rmpi", .Platform$dynlib.ext, 
  error: dynamic/shared library '/home/john/R/i486-pc-linux-gnu-library/2.11/Rmpi/libs/Rmpi.so' was not loaded
ERROR: loading failed

I am using Ubuntu 10.04.

I would greatly appreciate any help you can give.

John Joseph
