Yes. If you don't want X security, you must recompile Tk without 
security. Search unix/Makefile for "security" and rebuild/reinstall.

But it is so simple (after doing it -- it was a nightmare for me! :)
If you use "xdm" (or the kde or gnome derivatives) with xfree, 
security is on by default. If you use "startx", you might need to 
create a "~/.xserverrc" where you specify the Xserver command line 
with the -xauth option, e.g.,

> cat ~/.Xauthority
exec /usr/X11R6/bin/XFree86 -dpi 100 -depth 16 \
-auth ~/.Xauthority

if you have a ~/.Xautority, then it is probably OK, just "startx". If 
xclients don't start, kill the xserver, remove ~/.Xauthority, and 
start "xauth", adding your host, e.g.,

> xauth
Using authority file /home/jcard/.Xauthority
xauth> add localhost/unix:0 . 1234
xauth> l
localhost/unix:0  MIT-MAGIC-COOKIE-1  1234
xauth> exit

and restart the xserver with "startx". If xclients dont start, go to 
1) (rebuild Tk without security :)
