Which of the many "flavors" of Python did you build?  I suspect you 
don't have the problem with a "pure Unix" build (such as Apple 
included...Python 2.2...with Mac OS X 10.2) but only with one of the 
forms that includes the framework stuff.

At least, I don't have the problem in 10.2 with the Apple-supplied 
build, nor did I have it with my own "pure Unix" build from last spring.
