A PCB distribution usually is set up so that PCB will automatically look in a packages subdirectory of the working directory. So, to make PCB find all the custom elements I put in gaf/pcb-elements I make a link in each of my project directories. Note that this link is actually not required when using gsch2pcb because, as described below, you may alternatively specify the pcb-elements directory in a project file. But if you do want to make the link, in directory gaf/myproject1 enter the command:
ln -s ../pcb-elements packages
