I use the Fink package manager and in the past have created local  
packages that build octave using various lapack versions. At the  
present time, I'm only using Apple's version.

However you might look to see what is done there, and modify it for  
your purpose. During the configure process I see the following

=== configuring in scripts (/sw/src/fink.build/octave3.1.51-3.1.51-3/ 
octave-3.1.51/scripts)
configure: running /bin/sh ./configure --disable-option-checking '--

'--mandir=${prefix}/share/man' '--libexecdir=${prefix}/lib' '-enable-

'--with-fftw' '--with-lapack=-Wl,-framework,Accelerate,-dylib_file,/

Perhaps there is enough information in that for you to figure it out?
