Hmm, maybe I misundertood what the program_path was for? The executable
method goes straight to the system path unless program_path is set, so I
assumed you would only set program_path if you specifically wanted it to
look somewhere else. You wouldn't get a warning if you didn't specify a
program_path and just left it to look in the system path.

One version of an executable in /usr/local, another version - which I
wanted to use in my home directory.
The program_path method gets a path from an environment variable, which
was set to ~/.
I didn't realise I had the wrong permissions on the
executable though, and it was silently failing to use my version and using
the one in /usr/local instead.
