You could try rebuilding databases/db/v4 with MODTCL_VERSION=8.6 added to
the Makefile and see if that helps at all..

Thanks. I wasn't sure and the tclsh import didn't work for either 8.5 or 8.6
for me.
Thanks for LD_PRELOAD, about which I knew nothing.
The kludge got rid of all but one undefined symbols:

so I tried building from ports, building Python against Tcl/Tk 8.5 because
I could see what to change in Makefile.inc with some confidence I was
guessing right (8.6 > 8.5 about line 100). Same result, first with package
command:

And with the load command:

Give up on kludge I think.
