Some of these were pointing at archive.apache.org. Now they aren’t, I investigated for good rationale for using the archive before altering it.
mod_python still uses archive.apache.org as that is the only place it exists that I could find.
jsvc *now* uses apache.archive.org as the formula was otherwise broken and the binary tarball it needs no longer exists on the main mirrors.
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.
