What I did was to place my Fink libs ahead of the standard ones in LDFLAGS ...

        export PREFIX="/sw"
        export LDFLAGS="-L$PREFIX/lib -L/usr/lib -m32"

For MacPorts, the same should work by changing the prefix to "/opt/local"

To make sure you get it right, use "otool -L src/.libs/octave" to see which 
readline dylib Octave is linked to.  Near the bottom of the list, I see ...

        /sw/lib/libreadline.5.dylib (compatibility version 5.0.0, current 
version 5.0.0)
