openoffice.org-calc depends on libufsparse which depends on 
	lapack3 | atlas3-base....

So if you install OO.org before Octave, you will get lapack3. I wonder if 
libufsparse should list atlas3-base before lapack3.

I'm not happy with that. It's possible to use Octave with a specific 
BLAS-library not provided by Debian (for example Goto Blas). And in reality, 
atlas3-base is not what you want -- you want one of the tuned atlas3-sseX or 
atlas3-3dnow packages. 

Rafael, should we add a 
	Recommends: atlas3-base 
to Octave?
