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.
GNU GetText breaks eg. Ruby 1.9 builds, and some other formula I have been building too. But it is required by eg. glib. So to solve this we are going to by default not symlink gettext into the Homebrew prefix.
Formula that depend on GetText will have the gettext paths added to the brewing environment automatically. Neat.
All Gettext binaries fail at runtime with linking problems related to the
environ variable. According to <http://www.mail-archive.com/bug-gnulib@gnu.org/msg09272.html>
the environ variable is missing from some platforms (between them MacOS X),
and autoconf test for it, and sets HAVE_ENVIRON_DECL accordingly. A common
workaround was declaring "extern char** environ" in the code if the OS didn't
provide the environ variable, but that doesn't work since 10.5. Since then you
have to use _NSGetEnviron() function declared in crt_externs.h. This
workaround works at least since 10.3. t
