Hey David/Beowulf Gang,

Sorry for your PVM woes, but please try the latest "patch pre-release"
version of PVM, 3.4.5+7 available at:

	http://www.csm.ornl.gov/~kohl/PVM/pvm3.4.5+7.tar.gz

This likely fixes many recent problems, especially on 64-bit arches.

(Yeah, I know, another full release would be handy sometime...  :-})

In the future, please don't hesitate to email:

	pvm at msr.csm.ornl.gov

with any PVM-related questions or concerns.

We're unfunded but not dead yet...  :)

All the Best,

	Jim
