Hi, so yes I'm trying to install the source but after installing, it does not seem to be able to locate the libraries.
mpirun gives the error libopen-rte.so.0: cannot open shared object file: No such file or directory Of course, I have seen this faq http://www.open-mpi.org/faq/?category=running#adding-ompi-to-path But this is more than a little beyond me. The libraries seem to be installed in usr/lib, (at least, that's where it locates the library in question.) but I can't seem to get this to work by modifying LD_LIBRARY_PATH, or using the --prefix switch. Obviously I am doing something very wrong, never having bothered with editing paths before. (This is why I use packages.)
