+Under OSX, there is a choice you need to make.
+ Apple ships its own build of Python, which lives in the core OSX filesystem
+ hierarchy.
+ You can also manually install a separate Python, either purely by hand
+ (typically in 
+\family typewriter 
+/usr/local
+\family default 
+) or by using Fink, which puts everything under 
+\family typewriter 
+/sw
+\family default 
+.
+ Which route to follow is a matter of personal preference, as I've seen
+ users who favor each of the approaches.
+ Here I will simply list the known installation issues under OSX, along
