You should leave off the MACOSX_DEPLOYMENT_TARGET unless if you really need to
use a feature that is only available in 10.4.

It's a wiki, so the set of maintainers contains you, too.  :-)  In particular,
people who have found problems and solved them are often the best people to
write documentation about how to avoid such problems. If you have the time, we
would appreciate your fixes to that page.

I may have fixed that in numpy SVN; I'm not sure.

The check_dot failures are known and we have a fix thanks to David Cournapeau
that will probably make its way in soon.
