There may be another problem, but since you're building a 64bit app you'll need
to take care of a bug in Apple's blas.
The problem is discussed in the developer's copy of README.MacOS
http://hg.savannah.gnu.org/hgweb/octave/file/64ae43e0e1c0/README.MacOS
There is a patch intended for the developer's sources at the link below that
will allow the configure script to detect the problem and apply the wrapper.
