I checked both with find and locate before I posted the question. Before that I had run updatedb many times, due to a Linux.-class I'm taking. They just weren't there... After installation it worked without any problems. $PATH didn't need any changes.
But tnx for a very informative reply. If I hadn't done it already, it would've helped a lot!
Btw - I got the pinfo instead of info, and I'm very happy with it...
