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

[Adam T. Moody]

Hi Hari,
The systems are down at the moment, so I can't test your suggestion.  
However, I suspect adding a path here won't help. You can see the 
configure output tested and found PSM, but it opted to use PSM2.

checking psm.h usability... yes
checking psm.h presence... yes
checking for psm.h... yes
checking psm2.h usability... yes
checking psm2.h presence... yes
checking for psm2.h... yes
checking for psm2_init in -lpsm2... yes


The subconfigure.m4 for the PSM channel is missing the case where 
someone specifies --with-psm explicitly.  For that case, it falls back 
to look for both PSM and PSM2 and then uses PSM2 if it finds it.  The 
patch here should handle the --with-psm case to force the build to use 
PSM on a system that has both installed.
