I have xcode installed but I don't know how to use it. What do I have to do to get to the point where I enter the commands in the read me file?

@gmay What version of Pd are you using? In the newer versions to install zexy just go to menu > Help > Find externals, type zexy and click on the first hit (2.2.8 Darwin). Then go to menu > Pd > Preferences > Startup.., click "new" and type zexy. Restart Pd and you should be able to use the objects from the library.

Thank you! I read the install instructions in the zexy files and got way off course.
