Why don't you have your binaries installed in a user-owned directory like ~/brew or whatever, and then put that at the front of the path? Asking people to `chown` a system path is plainly a contravention of the principle of least privilege.

`~/brew` varies from username to username and requires us to be able to relocate all binaries so they reference the correct path. We do this for as many as possible but it's not possible for all of them.
