System: NetBSD 3.99.15 NetBSD 3.99.15 (GENERIC-1.696-20060125) #8: Wed Jan 25 04:59:39 ICT 2006 i386
	packages compiled using pkg_comp with libkver and 3.0 release sets
Architecture: i386
Machine: i386
	misc/visual-regexp installs with any version of tk >= 8.3.2
	(which obviously includes 8.4.12nb2 (the current x11/tk)
	which is what I have installed.   However, when installed, the
	visual_regexp script wants wish8.3 which only gets installed
	with x11/tk83.   There doesn't seem to be any good reason for
	that, from what I can tell (very minimal testing) it works
	fine with tk 8.4.12

	Also (very minor bug, but which perhaps can get fixed at the
	same time), the Usage string in the help window (once you
	have visual_regexp working) says
		Usage: tkregexp <sampleFile>
	where it probably should say
		Usage: visual_regexp <samplefile?

	I don't know who/where/when the name was changed from tkregexp
	to visual_regexp (ie: whether this is a pkgsrc name change, or
	something done by its author) so I don't know if this one is
	one that should be sent back to the author to fix or not (if it
	should, then it isn't important enough to bother with a pkgsrc
	patch to handle in the interim)

	Install (or update to) current versions of tk (and anything else
	that requires), and then install misc/visual-regesp

jade$ pkg_info | grep ^tk
tk-8.4.12nb2        Graphical toolkit for TCL
jade$ pkg_info | grep ^visual
visual_regexp-3.0nb1 Easily design and debug regular expressions graphically

	Then look at the start of /usr/pkg/bin/visual_regexp (obviously
	using whatever LOCALBASE you're using)...

jade$ sed 8q /usr/pkg/bin/visual_regexp
# the next line restarts using wish \
exec wish8.3 "$0" -- ${1+"$@"}

set version 3.0

	Note the "exec wish8.3" which is expecting a version of Tk
	which I don't have installed (and which pkgsrc did not
	install for me).

	If you make it work (by changing the 8.3 to 8.4 - or, I
	assume, by installing x11/tk83, then click on the help
	button in the upper right corner of the main window to see
	the help page with the erroneous usage string.

	Do some of the install script munging that pkgsrc is good
	at to convert the "wish8.3" string into whichever version of
	wish is actually installed.   Either that, or simply change it
	to use "wish" instead of being pedantic about which version
	it wants.   Alternatively, I suppose it would be possible to
	have it demand that tk83 be installed, rather than any tk
	after (or exatlY) 8.3.2 - but there doesn't seem to be a need
	for that, given that it seems to work OK using 8.4.12.
