I do not fully understand these OS X / Darwin version numbers.

This page:

http://en.wikipedia.org/wiki/Darwin_(operating_system)

appears to show a relationship between Darwin release numbers and OS X 
releases. 
  From that, Darwin 7.0 would be OX 10.3, which you say Sage has never been 
built on.

If that is so, does it seem reasonable to display a message about being 
unsupported for Darwin versions 1.3.1, 1.4.1, 6.0.1 and  7.0 ?

If I interpret that table correctly, and the links, that would be OS X 10.0 
(Cheetah), 10.1 (Puma), 10.2 (Jaguar) and 10.3 (Panther).

Any such tests in configure scripts are probably going to be untested, unless 
someone has the older versions.
