Regarding to my tutorial for building SuperTux 0.3.2 SVN on Mac OS X Snow Leopard i updated the tutorial for Mac OS X Lion and the new location from the SuperTux Sourcecode.

I also build a version for download if you don’t want to build it: SuperTux 0.3.3 for Mac OS X Lion

Prerequisites

Install HomeBrew:

/usr/bin/ruby -e "$(/usr/bin/curl -fksSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"

Install needed requirements:

brew install libvorbis physfs glew sdl sdl_image boost

Build SuperTux

git clone https://code.google.com/p/supertux/
cd supertux
mkdir dist
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=../dist/ -DCMAKE_BUILD_TYPE=RELEASE
make install

If all works SuperTux.app should be in the dist folder.
