[Haskell-cafe] ANNOUNCE: vacuum-cairo: a cairo frontend to vacuum for live Haskell data visualization

[Ross Mellgren]

Unfortunately the .DMG based frameworks do not have the cairo svg  
framework (or the opengl framework), and it's non-trivial to get it  
added on. If you need it, best bet right now is probably to go for a  
macports install.
