That's it!  That's the error.  I've appended the patch 
file to fix it.  Save the appendix into a file (e.g. 
blt-patch-for-Swarm-with-tcl7.6) and go into the blt2.1/src
directory and apply the patch:

   % cd blt2.1/src
   % patch < blt-patch-for-Swarm-with-tcl7.6

Then recompile blt.  You should now be able to use Tcl/Tk 
7.6/4.2.

Hmmm.  See if this fixes  things.  If you're still getting
these errors after you use the new blt & tcl 7.6, then 
we'll address those.

p.s. I thought I'd sent the patch to the list before; but,
that was in the heat of SwarmFest, so I may have forgotten.
Sorry!
