Thanks, Ralf.  Indeed, we have no reports of problems on OSX 10.6, and it is 
likely there have been many tests on that platform.  So a test of numpy on 10.5, 
independent of Sage's build process, would be useful.

I don't have access to a Mac, but I posted your suggestion to the Sage ticket 
for this, where hopefully somebody will take it up.
