Doris, 

glad you got it to work. 

The ownership is most likely not an issue. When you install HomeBrew it prompts you to change ownership of /usr/local to yourself so that you don’t have to use “sudo” all the time. The best time to do it is before you install anything else, otherwise you have to do a recursive “chown -R”, as you have seen from the stackexchange link. By the way, it’s probably better to chown to yourself:wheel, instead of yourself:staff. 

Also , brew symlinks into /usr/local, by default, so you would find your library in /usr/local/lib/libgs.9.53.dylib (shorter path).
