S.O.S. Mathematics CyberBoard

I've downloaded the LaTeXiT-2_0_1.dmg from the Apple software site. When I try to use it, a prompt pops up that says "pdflatex not found or does on work as expected" and "gs not found or does not work" and "ps2pdf not found..."

I couldn't find these anywhere on the internet by doing a Google search. Does anyone know what I should do?

you probably need to install pdflatex, ghostscript, and ps2pdf ... no idea how it works on macs though
