The emacs-yaml package is configured to build against emacs-minimal,
which seems to work.  When you however switch to emacs package, it takes
way to long to build, much longer than compiling for example firefox
package.  That feels off.

The difference is huge.  The process taking vast majority of the time
(in the emacs version) is this one:

--8<---------------cut here---------------end--------------->8---

I do not know enough to even guess what could be the problem, but it was
suggested I should bug-report this.

Cheers,
Tomas

Closing it then!

Notice the -done that does the job ;)
