This automator installation package will install recent SVN builds of Numpy (1.1) and Scipy (0.7), as well as Matplotlib (0.98), iPython (0.8.3) and PyMC (2.0 beta) for OS X 10.5 (Leopard) on Intel Macintosh.
Mac OS X installers for several important scientific computing tools, using recent builds from svn or cvs. I will attempt to make these weekly builds, where appropriate.
