Hmph ... how are you starting the server exactly?
I now notice that you're running on OS X ... what version of that? Do you have SIP enabled? SIP has been known to break stuff like this; in particular I'm thinking of its habit of silently suppressing key environment variables like DYLD_LIBRARY_PATH at inopportune times. If your setup is such that your psql needs that set to start correctly, that could be a place to look for an explanation.
A related thought is that maybe PATH in the server is different from what you have interactively, so that it's not finding psql, or finding the wrong copy. Specifying a full path to psql in the invoked script would help narrow that down.
