Yeah, I thought this the other day when I forgot why I put it first for now and broke my setup on my work machine.

The problem with this is that `bash_exports` requires `brew --prefix` to be known - https://github.com/necolas/dotfiles/blob/c73dc9c4b999d7d6ba50ce098c149d3cf768ba28/bash/bash_exports#L26-L27 - and with this change it won't be if your Homebrew installation is not in `usr/local`.

Any ideas?
