Unable to remove mpi-selector for OFED 1.5.3 during uninstallation

If  you encounter this error "cannot remove mpi-selector" when uninstalling or even installing OFED package, it is best to exit the package and do a yum remove mpi-selector. Apparently, there there are a number of dependencies to BLAS, Scalapack etc.

# yum remove mpi-selector.

Later you can reinstall the dependencies like BLAS, SCALAPACK etc
