?

 ls -l /usr/lib/liblapack.dylib
lrwxr-xr-x 1 root wheel 118 Jul 21 18:04 /usr/lib/liblapack.dylib ->
../../System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libLAPACK.dylib


(on 10.7 at least)

It works on 10.7 (no ATLAS).

I went ahead and added a separate -atlas variant (I didn't notice
initially that it was using LAPACK), but I didn't reproduce this
problem on my 10.5/powerpc octave324-atlas install.  I'll try
10.6/x86_64, too.
