My first attempt went pretty straightforward.  Note everything I'm talking
about here is in the install tree.

First, pkgIndex.tcl wasn't being installed, so I copied it to
$prefix/lib/plplot5.1.0/ by hand.

pkgIndex.tcl then needed updating.. I changed the first few lines to:

if {$tcl_platform(platform) == "unix"} {
    if {[info exists tcl_platform(debug)]} {
        set file [file join $dir drivers tkwind_drv[info sharedlibextension]]
    } else {
        set file [file join $dir drivers tkwin_drv[info sharedlibextension]]
    }

Then I did:

wish
% package require Plplotter
5.1.0

so all appears well so far.  Note I didn't have to add anything to auto_path
b/c I have wish installed in the same local dir tree as plplot.

But then unfortunately in trying to run the demos I get:

% source runAllDemos.tcl
Unable to locate dispatch table initialization function for driver:
tkwin_drv.so.
Segmentation fault

So then I tried:

$ cd $prefix/lib/plplot5.1.0/examples/c
$ make x01c
$ x01c -dev xwin
Plplot library version: 5.1.0
Unable to locate dispatch table initialization function for driver:
xwin_drv.so.
Segmentation fault

Also using the tk driver segfaults as well.  So all is not well in
install-land.

I have no idea what's going on, and didn't write the dynload code (in fact
have been using static drivers up to now), so that's probably all I will
do on this for now.  I may take a look at getting the static drivers
working again (broken pretty badly now from the looks of it).
