Which editor opens up? I kind of believe the only way to get the issue
you have is that /usr/bin/emacs exists, but doesn't point to Emacs, but
to some other text editor.

And this gets clear now: you don't have Emacs installed, but you have
Jove (http://en.wikipedia.org/wiki/JOVE). The thing is that Jove is
pretending to be compatible with Emacs, but it's not, so it makes the
autoconf stuff think there is Emacs, even though Emacs is not here.

As a workaround, you can apply this patch:
diff mbox
