Thank you for your answear. The thing is, I read that text and could not understand it. Therefore I searched for another tutorial and came across some youtube ones.. I come from a Windows environment and has troubles locating usr/local/lib and include. I have googled for a way to find those folders but with no luck. (All I seem to find it to hit shift-cmnd-G and type it in, but it says folders does not exist).
I will google some more and hopefully get this thing to work somehow.
