That should work.

Here's what I tried:

 * Created a directory "demo".

 * Created a subdirectory "demo/demo".

 * Added "demo/demo/setup.rkt" as

    #lang setup/infotab
    (define raco-commands '(("demo" demo "run Demo" #f)))

 * Added "demo/demo/main.rkt" as

    #lang racket/base
    'Demo!

 * Installed with `raco pkg install --link demo'

    [This step internally runs `raco setup demo', which registers the
     `raco-commands 'spec of "info.rkt" and makes the `raco demo'
     command available.]

 * Ran `raco demo' => got "'Demo!" as output.

Since it's not working for you, I wonder what `raco setup frog' says.
Does it seem to set up the `frog' collection? And does `raco frog' work
afterward?
