The line endings problem was easily fixed using the

tr -d '\r' <file.in >file.out

command.

Once that change was made, the patch applied cleanly, and plplot was
configured and built without errors and similarly for

make cdemos fdemos cxxdemos tkdemos

Furthermore, all my tk interactive tests worked fine (and I liked the page
control you now have for the tkdemos.tcl demos).

However, pltcl no longer works.

./pltcl -dev xwin
application-specific initialization failed: Can't find a usable plplot.tcl
in the following directories:
    /usr/lib/plplot5.1
/home/software/plplot_cvs/HEAD/plplot_darley/lib/plplot5.1
/home/software/plplot_cvs/HEAD/lib/plplot5.1
/home/software/plplot_cvs/HEAD/plplot_darley/library
/home/software/plplot_cvs/HEAD/library
/home/software/plplot_cvs/HEAD/plplot5.1/library
/home/software/plplot_cvs/plplot5.1/library



This probably means that plplot wasn't installed properly.

This is undoubtedly a configuration issue.  The point is that stuff built in
plplot_darley/tmp should just work without installation so long as you stay
in that directory.  (Once plplot is installed, that should work as well with
whatever install location prefix is used, but I haven't gotten that far,
yet.)

Note, there is a plplot.tcl in the current directory,
/home/software/plplot_cvs/HEAD/plplot_darley/tmp.
Vince, what environment variable do I need to set (or what change to source
files) to put the current directory on the list of directories to be
searched for plplot.tcl?  Once this is sorted out so I can successfully
run pltcl, then that will complete my tests, and I intend to commit
your patch to cvs so others can give it a try.
