I had a LOT of problems with RH7.0, to the point that the workstation crashed 
and was totally unusable, and the desktop manager didn't work.  Upgrade to 
RH7.1, and everything seems to be working fine.  I've got cns and ccp4, among 
other things, working and running again.

I'll also note that there were problems compiling with the RH7.0 fortran 
f77/g77 compiler, but absolutely no problems with RH7.1!

One other note.  In the auto-amore script, it uses "nawk" in the unix example.
 You need to replace that (also in the auto-sphere subroutine) with "gawk".  
Maybe all of these will be awk again.  "nawk" is from "new awk" and "gawk" is 
from "GUI awk".
