How I Build Emacs Now

So a while ago I posted a hideous shell script that I use to build Emacs on OSX. It was hideous and awful and didn’t in fact solve the problems that I wanted it to.

My requirements:

  • don’t build what you don’t have to;
  • personal configuration should live in ~/Library
  • shared configuration should live in /Library
  • the warning about the missing arch-dependent data dir makes me mad enough to punch a nun.

So I’ve hacked together the following, which:

  • updates my bzr checkout;
  • builds a non self-contained Emacs;
  • points the various directories that would live in /usr/local to where I want them;
  • is doubtless full of bugs.

But I figure, share and enjoy. There are probably, what, four people in the world who might find this elucidating?
