When tping hangs, can you check to see if the lamd is still running on all
the nodes? One of the reaons that tping (and lamhalt) may hang is if a
lamd fails/aborts.
If this is what is happening, it is quite possible that the RPM you
installed is not compatible with your system (there's a million reasons
this could be happening). It may be advistable to either build from
source or download the SRPM and rebuild it for your system (see the thread
that just wrapped up about your installed version of Libtool!
http://www.lam-mpi.org/MailArchives/lam/msg08359.php).

Note that LAM can do this as well; if you uninstall the RPM and build LAM
from source in a directory that is accessible on all nodes, it can be an
easier software management solution in many cases. See the LAM FAQ for
more details here ("Typical setup of LAM").
Hope this helps.
