The binary support module (1.1) fixes the gremlins issue if you put
vt_enable_binary.tcl into your tcl folder. It renames your ns_return, ns_write,
and ns_uuencode to use it's own version which are TclObjCommands.

Note that I just added ns_uuencodebinary today from Vinod's patch. I'd
appreciate any testing and feedback possible.
