[mvapich-discuss] Forcing PSM on a machine with both PSM and PSM2 libs

[Adam T. Moody]

Hello MVAPICH team,

I have a machine that has both PSM and PSM2 installed.  I would like to 
create a build that links to PSM, but configure always picks PSM2 if 
it's available, even if I specify "--with-device=ch3:psm --with-psm".  I 
think the following patch would help, although I've not been able to 
test it yet.

Can you verify this?

Thanks,
