The diffs below show which files in the usual dstool distribution
(after YES to gcc, NO to FORTRAN, NO to TCL) need to be
edited for redhat 6.1 with xview as in:

*************************************

rpm -q -a | grep xview
xview-3.2p1.4-4
xview-devel-3.2p1.4-4
xview-clients-3.2p1.4-4

*************************************

and environment variables

printenv DSTOOL
/local/dstool_2.0

printenv OPENWINHOME
/usr/openwin
*************************************
Diff printout below comes from script:
foreach i ( `cat hc_files` )
foreach? diff dstool_2.0/$i dstool_2.0_orig/$i >> difflog
foreach? if ($status) echo "ABOVE from $i" >> difflog
foreach? end
