Congrats ! you’re going forward fast. You installed successfully the homebrew package management and the required 3rd party software tools and libraries. Compile & link from the command line works too, but now you’re now stuck with activation.
According to the HOWTO install a LIBPF SDK for OS X, “To run your models section”, to run the developed models you also need to activate LIBPF™.
The easy way is to install one of the LIBPF™ demos, launch the User Interface and perform the automatic activation (menu Settings -> Activate). For more details see the LIBPF™ Activation Guide in the user manuals page.
