The question is not whether the libraries are installed, but whether your 
dynamic linker finds them, which it doesn't. In this case, you need to figure 
out where the library file (liblamf77mpi.so.0) is located, and add that path 
to your LD_LIBRARY_PATH environment variable (in bash, that is "export 
LD_LIBRARY_PATH=<path-to-lib>"). Note that LAM uses a daemon, which needs to 
be restarted after changing the environment variables. Typically, you need to 
run lamboot again.
