[BioC] Rmpi loading error

[Ye, Bin]

Hi, Everyone,

WE have R 2.2.0 installed on linux (federo), and lam/mpi installed under /usr/local/lam-7.1.2, installed Rmpi_0.5-2 without an error. But when try to load the library get error as below:
> library("Rmpi")
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library '/usr/local/lib64/R/library/Rmpi/libs/Rmpi.so':
  libmpi.so.0: cannot open shared object file: No such file or directory
Error in library("Rmpi") : .First.lib failed for 'Rmpi'
Error in dyn.unload(x) : dynamic/shared library '/usr/local/lib64/R/library/Rmpi/libs/Rmpi.so' was not loaded

liblamf77mpi.so.0  liblammpi++.so         libmpi.a

The libmpi.so.0 is there, and the path is correct, why Rmpi can't find libmpi.so.0? 
Thanks a lot in advance!
