Add rust-mode to the build

[brson]

I'm often on an old version of rust-mode because I don't get around to recompiling it. Would be nice if it was part of the build. Need to autodetect whatever dependencies it has.

You should try getting it from MELPA, this will guarantee you get the latest (daily) snapshot, allow you to manage updates and also handle the compilation for you (for all its deps as well).

Oh, that sounds like a much better solution. I will look into that.

I installed emacs 24 and learned to use the package manager. Very cool.
