More info.  From the tmp dir:

$ wish
% puts $auto_path
/usr/lib/tcl8.3 /usr/lib /home/mjl/gts/lib /usr/lib/tk8.3

% source pldefaults.tcl
% puts $auto_path
/usr/lib/tcl8.3 /usr/lib /home/mjl/gts/lib /usr/lib/tk8.3

% load drivers/tkwin_drv.so Plplotter
% puts $auto_path
/usr/lib/tcl8.3 /usr/lib /home/mjl/gts/lib /usr/lib/tk8.3 /home/mjl/gts/lib/plplot5.1.0/tcl

So it's the pkg load that modifies auto_path, adding
$prefix/lib/plplot5.1.0/tcl.  So far so good.

The problem is then that the tmp/tclIndex file is copied to that location.
Since tmp/ has access to all the *.tcl files, tclIndex contains references
to all of them.  But then it is not correct for the install dir.  A proper
tclIndex file needs to be made-in / copied-to that dir.
