Thanks, but of course a.I should work, right?

Thanks again,  it would be nice if you could help us by checking out an 
SVN version before a release ;-)

But, better late than never. 

Also, show-stopper might be a bit of an over-statement.   A dumb error, 
yes.   But, if you really depend on this, then it's a simple fix to 
place a from numpy.lib import * at the top of the linalg.py file.

Thanks again for your help.
