List /usr/pkg/bin earlier in your $PATH. As you mention later, it's
probably not a good idea to delete or replace standard executables
in /usr/bin (et al).

Yes and no. If you invoke "ssh _machine_ command", you will need to
specify the command with a full path, otherwise SSH is going to look
for the command using the path compiled into SSH.
However, if you invoke just "ssh _machine_" to get an interactive
shell, SSH ought to give you a "login shell" which sets up the full
environment and would read a ~/.profile. You can double-check this
by taking a look at "ps aux" or equivalent, and see whether your
shell was a login shell by seeing whether there is a "-" in front of
Try adding this to your .profile:
...and compare what you get from "echo $PATH" when you ssh to a
ssh _machine_ ...versus...
ssh _machine_ /bin/sh
