Updates to upstream version 2.00.2. Now declares 'pcre' as a package
dependency. Patches Makefile.in such that brew's environment variables, namely
CPPFLAGS and CFLAGS, are passed to autotools.

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.
