You're free to add corrections to the wiki. Try your best to follow the existing style. IMHO, the OS X page needs to be split by version (e.g. 10.5, 10.6). One of the reasons for the Python incongruity is that older versions of OS X generally came with very out-of-date Python releases. Also, Snow Leopard's transition 64-bit transition broke important dependencies like wxwidgets, which makes Snow Leopard less compatible with ROS than 10.5. Thus, it seems increasingly the case that OS X installation needs a different approach to handle these divergences, as attempting to rely on Macports across multiple OS X releases has proven to be very slippery. - Ken On Mon, Aug 30, 2010 at 2:01 PM, wrote: > I can confirm that I had the same problem on Snow Leopard and this solution > worked. > > What is the edit policy on the ROS wiki?
