It looks like you might have a messed-up installation. You have several
include files around the place, and you're getting different errors now.
Why don't you try and get to a stable base point to start with? The
includes in /usr/include might have come from part of your standard
*nix/*nux installation, depending on where you installed LAM (where did
you install it?). Get rid of as many of the other LAM or MPI pieces on
your system (if it's your system).
Reconfigure LAM with a unique installation location that's not part of the
standard system, like /usr/local/lam-7.1.1 or /home/srini/lam-7.1.1
"./configure --prefix=/usr/local/lam-7.1.1" etc. Then rebuild BLACS
pointing at that particular version of LAM. This won't take long, and
you'll know you're using just one LAM. Then see if you can get repeatable
behaviour.
