wget will find and use libidn if it is present, which uses gettext.
This dependency was not captured in the wget formula.
To keep things simpler, the user must now opt-in to libdin by brewing
with "--enable-iri". Without this flag, we tell configure not to look
for libidn.
FixesHomebrew/homebrew#1105.
brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
Moved Forumla and Cellar/homebrew into Library.
This way the homebrew core files are more sensibly placed, Cellar is
more internally consistent and only generated. And Homebrew is ready for
use straight out of the tarball.
