waf miscompiles py2cairo on Lion, linking the wrong Python Library when HB Python is installed. So add a LINKFLAG that sets the path to the real python Library as determined by `python-prefix`, where it gets used at link time and fixes the problem where you can't import cairo into Python. Also add a `fails_with :llvm` block to work around a build error where waf tries to optimize with `-march=native` which llvm doesn't accept. https://bugs.freedesktop.org/show_bug.cgi?id=51544 Tested on Lion and SL using system Python, HB framework Python, HB non-framework Python with clang building both native and universal binaries, by importing the cairo module into Python. Rebased on Homebrew 0.9.2 Fixes Homebrew/homebrew#12893 Closes Homebrew/homebrew#12943. Signed-off-by: Jack Nagel <jacknagel@gmail.com>

For non-homebrew Python, you need to amend your PYTHONPATH like so:
|
|
export PYTHONPATH=#{HOMEBREW_PREFIX}/lib/#{which_python}/site-packages:$PYTHONPATH
