Hi Miguel Two comments on your comments:
1. Defining LD_LIBRARY_PATH should not be necessary in my case because the libraries are in /usr/local/lib, a standard place for ld to look for shared libs. I did not define PATH either and Linux is able to find the executable MPI binaries in /usr/local/bin because it is a standard location for Linux. 2. I defined LD_LIBRARY_PATH (regardless of whether it should be necessary) manually, like this: bash: export LD_LIBRARY_PATH=/usr/local/lib If this would have worked, I could have added this to my .bashrc Again, any help is deeply appreciated.

Where did you add your LD_LIBRARY_PATH ? make shure it is in one of the profile files for your shell.. such has: .bash_profile and _not_ .bashrc that's a tipical error in these kind of configurations.. best regards Any help is greatly appreciated.
