s/require 'brewkit'/require 'formula'/g 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. 2009-10-15 08:07:12 +00:00			`require 'formula'`
Fix SDL pc files and sdl-config So many tools expect all SDL modules to be installed in the same place. So we have to change the prefix path to HOMEBREW_PREFIX. This is probably the correct thing to do in general in fact. 2009-10-23 18:02:02 +00:00			`require Formula.path('sdl')`
sdl_image formula We depend on newer libpng than OS X provides because the libpng version has bugs that exhibit themselves for some uses of the SDL. See issue Homebrew/homebrew#89 for more information. 2009-10-12 02:31:40 +00:00
