There are several ways.  Probably the simplest is to put the path to
the desired one before /usr/bin in the PATH.

In your /etc/profile, there are several adjustments to the path.  Then
it sources all the applicable shell scripts in /etc/profile.d/.  For
all bash users, add this file, let's call it new_wish.sh, to
/etc/profile.d/:

------ snip 8< here ------
# Add /usr/local/ActiveTcl/bin to the PATH so that wish users
# get that one before the stock one in /usr/bin.
pathmunge /usr/local/ActiveTcl/bin
------ snip 8< here ------

Be sure to "chmod +x new_wish.sh".

Dealing with (t)csh users is left as an exercise for those who grok
(t)csh.
