I admit that it's a bit late :-), but I've sorted out the minimal necessary steps since I had to do it again. Here goes the list of the required ports:

linux_base-fc-4_13
linux-sdl-1.2.10,1
linux-sdl_image-1.2.5
linux-sdl_ttf-2.0.8
linux_dri-7.0

Just install these along with the required dependencies, and you should be set to go! Exact versions do not matter, just compile the latest stuff from ports.

Also, you will probably need the correct drivers with functional OpenGL hardware support for your current card.

Mine is GeforceMX4000, supported by the legacy driver nvidia-driver-96.43.07. I am not sure how well are ATI chips supported (if at all).

Works under FreeBSD 7 too!
