guys--
I also ran into problems with the cfs random number generator - on
linux 2.2.12. I also patched it by using /dev/random, which should be
better anyway. I previously posted my patch at
http://schwieters.org/cfs-1.4.0.beta2cds.patch.gz
The patch also fixes ccat and ccname to work with the latest
cfs formats.
