You are welcome.  My presence on the ompi-devel list isn't totally 
passive. :-)




I've incorporated this into OMPI -- Paul, can you confirm that I 
obeyed the license requirements properly?


IANAL, but looks all proper to me.

May I suggest that "Portions of this file derived from GASNet v1.12" 
might be clarified to indicate what portion(s).  Otherwise projects that 
"derive" from OMPI's configure might be expected to acknowledge GASNet 
simply because they cannot distinguish the origin of whatever they 
borrow from OMPI.  [discussion of viral license terms omitted].

On can't disable the option, but one can prevent confusing the user by
(partially) igonoring it.
In GASNet we dealt with this problem by detecting that the prefix,
suffix or transform options had been given and generate an error message
telling the user:
  This configure script does not support --program-prefix,
--program-suffix or --program-transform-name.
  Users are recommended to instead use --prefix with a unique
directory and make symbolic links as desired for renaming.

We can't; it's part of the built-in Autoconf options.  :-(

Perhaps it should be taken out of the help message in the configure 
script then.

Sorry!  :-(

Not a solution, but what we do here is to arrange our
installs into separate locations thus:

/usr/local/openmpi-gcc/$version
/usr/local/openmpi-intel/$version
/usr/local/openmpi-pgi/$version

and then use Modules (modules.sf.net) to let users easily
select which they want to use, so to load the default OMPI
for the Intel compilers they do:

module load openmpi-intel

We use symlinks for the module files to a generic one which
uses some lrange and split in tcl to derive the application
and compiler from the name of the module and loads the
compiler module if it's not already been loaded.

Users load a "vpac" module from their profile/cshrc at
login time and that pulls in our suggested defaults for
that cluster.

Makes life a lot easier for our users (and us!).

cheers,
Chris
