One of our students requested that we install MrBayes, software for the estimation of phylogeny on a genetic level. This is a fairly popular package which has been ported to numerous platforms so we thought we'd have a crack at installing it. Building the package on Scientific Linux was fairly easy with a few caveats. The base install is insufficient and requires readline-devel and ncurses-devel. Once these were installed the package compiled fine. Copying the package to a shared NFS software area is sufficient for all worker nodes to be able to run it. We compiled it with MPI options and it seems to respond happily to mpirun instantiations.
