slime-load-file is an asynchronous request (as it should be). you need
to wait until the file is done loading, and therefore the package
exists, before continuing.

you could use something like this to have the call block until the
loading is done (though this will block emacs as well): [totally

(slime-eval-with-transcript  `(swank:load-file ,"package.lisp")
                             (lambda (value)
                               (slime-repl-set-package ":lispdb")))

Ring the bells that still can ring.
Forget your perfect offering.
There is a crack in everything.
That's how the light gets in.
