hmm ... looking at your prior email, I see veclib is there twice 
"-Wl,-framework -Wl,Accelerate -Wl,-framework -Wl,Accelerate " AND atlas is 
there once "-lcblas -lf77blas -latlas".  If you want to use the accelerate 
framework, you shouldn't be linking to atlas.

Also its a good idea to avoid atlas for the dependencies.  You can check all of 
Octave's dependencies by ....

        port rdeps octave-devel

Perhaps if accelerate is used uniformly, there will be no seg-fault?
