(package-file "m-buffer.el") -- I mean, I've already told Cask about this.

Hmmm, okay. So cask then is setting my load-path to dependencies,
ert-runner is adding in files in the ./test directory? I guess this
helps in some way.

I didn't want to use an issue tracker to ask for help, and the only
mailing list that is mentioned in the documentation is cask-dev;
normally, I'd not send request for help to a -dev mailing list,
especially one with private archives.
