Subject: Re: [OMPI users] Open Mpi execution error

Deleting the install as you describe is a VERY bad idea. As I explained elsewhere, the system generally comes with an installation. Blowing things away can destabilize other areas of the system unless you are (a) very careful, and (b) very lucky

Just stay away from the system directories, please.
