One final thing.

Normally this should't make a difference - but if there is anything
related to petsc that might trigger wiered behavior with openmpi - in
this setting - this could be the one: Try compliling with minimal
compiler libs. i.e

gmake ex19 PCC_LNKER_LIBS=""

or

gmake ex19 PCC_LNKER_LIBS="-lf95"

or 

gmake ex19 PCC_LNKER_LIBS="-lf95 -lstdc++"

or

gmake ex19 PCC_LNKER_LIBS="-lf95 -lstdc++ -lgcc_s"

[the minimal set that works without link errors]
