Thanks for posting.

alist-get is a new Emacs feature, and Purpose should use it only when it's available. Does this error prevent you from using Purpose?
I work with two version of Emacs: 24.3 and the master branch. On Emacs 24.3 I also get this error message when Purpose loads, but it doesn't cause any problems when Purpose runs. On master branch I don't get any error, as alist-get exists there.

Purpose runs well, but can you adapt purpose on 24.4 to avoid that error,thanks!

Don't use built-in alist-get even if available #35

alist-get isn't available in any stable Emacs release yet, but
supporting it causes trouble with eager macro expansion (and therefore
compilation), even if that code is never called, so we have to drop it.
