here is the fix:

2007-06-29  Sam Steingold  <sdsgnu.org>

	* mpiexec (parse_global_args): quote ssi option values
	to allow multi-word values such as boot_rsh_agent "ssh
-x"
	(few): pass $ssi_args to lamboot

Thanks, you're correct that there is a problem with how
mpiexec  
passes SSI arguments to lamboot (or doesn't, as the case may
be).   
There's also a problem with how arguments are escaped, which
causes  
problems for arguments like "ssh -x".  I have
fixed both these issues  
in our subversion repository.  They will be part of the next
LAM/MPI  
release.

Thanks for bringing this to our attention,

Brian
