I wasn't clear.  Everything is fine in the tmp location.  It is the
installed location ($prefix/lib/plplot5.1.0/examples/c, for example) where
the make cdemos fails on RH 7.1 (but not on Debian/woody).  The tmp Makefile
has the -ltclmatrixd, but the installed examples one does not, and I am
about to fix that since it does make a difference for RH 7.1.

Yep, that works on Debian/woody as well, but not RH 7.1.

Actually, the test_tk.sh script I shared with the list before is an excellent
guide, but it needs a slight generalization so it can work from both
the tmp and installed locations.

Here is the modified script (it is set up for the installed examples
location, but set the first 4 export lines to . to work
from the tmp location.)
***********************
#!/bin/sh
#test suite of all interactive tk stuff that cannot be done by file.
#tk driver (x14c), tcldemos, tkdemos.
export cdir=c
export tcldir=tcl
export tkdir=tk
export plplotbindir=/usr/local/plplot/bin
$cdir/x14c
$cdir/x17c -dev tk
$tkdir/xtk01 -f $tkdir/tk01
$tkdir/xtk02 -f $tkdir/tk02
$plplotbindir/plserver -f $tkdir/tk03
$tkdir/xtk04 -f $tkdir/tk04
cd $tcldir
$plplotbindir/plserver <<EOF
plstdwin .
plxframe .plw
pack append . .plw {left expand fill}
source plgrid.tcl
proc 1 {} "plgrid .plw.plwin"

exit

cd ../$tkdir

Also, you must execute the following before this script if you want to
exercise the installed examples.

pushd /usr/local/plplot/lib/plplot5.1.0/examples/
cd c; make cdemos >&! make_cdemos.out; cd ..
cd f77 ; make fdemos > & ! make_fdemos.out ; cd ..
cd c++ ; make cxxdemos > & ! make_cxxdemos.out ; cd ..
cd tk ; make tkdemos > & ! make_tkdemos.out ; cd ..

Let me know whether the above works (once I make the commit of my
configuration change).

Thanks, Joao.  Please try this from the installed examples location as well,
once I get the configuration change out so the demo Makefile there is
correct for RH 7.1.
