I'm trying to use libpsm_infinipath but it complains about undefined 
references to knem_open_device and friends. What (packages) am I missing?

# cat  conftest2.c

/* Override any GCC internal prototype to avoid an error.
    Use char because int might match the return type of a GCC
    builtin and then its argument prototype would still apply.  */
#ifdef __cplusplus
extern "C"
#endif
char psm_init ();
int
main ()
{
return psm_init ();
   ;
   return 0;
}

# (yes configure wrote that for me)
#  gcc -o conftest2 -g -O2   conftest2.c -lpsm_infinipath -L/usr/lib

I'm actually trying to recompile mvapich2 with the Intel compilers ...
