I'd prefer not to install anything.  I do have the Git repo for ELPA,
though.  So could you please modify your recipe so that the required
packages are loaded from the Git repo (by modifying load-path), and
then the rest is done as needed?

Better yet, just post the file that causes the trouble, there's no
need for everybody to recreate it, right?

Thanks.
