 The default +universal variant doesn't work because cairo tries to
 determine the processor endianness at configure time, or rather, it
 assumes at configure time that there is a single endianness, which there
 isn't with a universal build. The developers of cairo
 [http://lists.cairographics.org/archives/cairo/2007-February/009523.html
 decline] to modify their configuration system to assist us. Therefore we
 must do it the hard way, building twice and lipo'ing the result together.
 Fortunately there is only a single library that needs to be lipo'd so this
 shouldn't be too much trouble. I'll try to adapt the universal build
 technique of the openssl port.
