Indeed, in the commands that I posted in a recent e-mail I did not run plinit,
as the README.tcldemos says to do. However, the x?? files each contain plinit
so it would seem to not be required to otherwise run it.
[This ^ is just repeating Arjen's new post.]
Also, this is what I take away from the readme: "To run individual examples,
run the x?? script corresponding to the x??.tcl example, where ?? is 01 through
19.?
In any case, here is what happens when I add that command:
MBPro:~ jerrybauck$ cd /usr/local/plplot_build_dir/examples/tcl
MBPro:tcl jerrybauck$ export PATH=/usr/local/plplot/lib:$PATH
MBPro:tcl jerrybauck$ /usr/local/plplot/bin/pltcl

When I execute x01 directly and choose xwin, an X window appears which is all
black and persists until I hit Return. If I choose qtwidget, a black 1/10
second window flashes that looks like it _could_ be the Qt widget. At the same
time, in my dock (which shows icons for running programs), an icon labelled
"pltcl" appears briefly. Also, this text appears:
*** PLPLOT ERROR, IMMEDIATE EXIT ***
plP_setphy: device minima must not exceed maxima
Program aborted
Sorry if I'm repeating myself but I just want to make sure I'm being accurate.

I ran a fuller test than I normally do (test_noninteractive in this case), just
to make sure that this is still true. At one point this appears in the output:
14: tcl
14: Missing examples :
14: Differing postscript output :
14: Missing stdout :
14: Differing stdout :
which I think confirms that the Tcl stuff is still working.

Not sure what this means. Is test_tcl_standard_examples a subset of
test_noninteractive?
