Thanks!  I've fixed the above problem now.

I haven't looked into this one yet.

I get that warning, but not with _just_ benchmark installed, so I'm
not quite sure where it comes from.

However, I don't see that error.  I'll see about 10.6/x86_64, though.

I get

Time for A'*B (A,B m-by-n matrices): 0.250954

on my 2.53 GHz Core2Duo (OS 10.7, so no ATLAS) and

Time for A'*B (A,B m-by-n matrices): 1.77265

on my 2 GHz G4 (10.5, with ATLAS).
