starting GNUstep applications in freeBSD 6.0release

[infosuffer]

i just recently setup freeBSD 6.0 with windowmaker as my WM. i thought
i would try some of these GNUstep apps to help finish out the desktop
but i cannot seem to figure out how to start any of them. i installed
several from ports and typing the name in a xterm does not work. ive
read somewhere that you need to use ./openapp or just plain old openapp
to get these apps working but have had no success with that either.
always returns "command not found"

anyways im excited to try out some of these cool looking apps!
gworkspace and project manager especially so any help is appreciated in
getting this stuff going. thanks.
