Problems updating math/maxima

My system: OpenBSD 7.3 GENERIC.MP#1125 amd64
The port: math/maxima

Hi Folks:

This port has not been updated for a while. I got permission from the
current maitainer to update it. I am having a little problem after
making the necessary changes to the Makefile. xmaxima will not
display. I get the following error when I try to run it:

$ xmaxima

Error in startup script: version conflict for package "Tk": have
8.5.19, need 8.6
while executing
"package require Tk 8.6"
(file "/usr/local/bin/xmaxima" line 5)

and the xmaxima shell script says requires tk8.6:

#!/bin/sh
# -*- mode: tcl; fill-column: 75; tab-width: 8 -*- \
exec /usr/local/bin/wish8.5 "$0" -- "$@"

package require Tk 8.6

<Snip>

maxima, the command line version, runs just fine. Below is my
Makefile. I have included MODTK_VERSION = 8.6

What am I missing here?
