I configured fltk-1.1.9 with the command

        ./configure CC=gcc-mp-4.3 CXX=g++-mp-4.3

and make sure that /usr/local/bin/fltk-config showed up in my path
before the macports /opt/local/bin/fltk-config.  Then I was able to
build octave-3.2.3 with

        ./configure CC=gcc-mp-4.3 CXX=g++-mp-4.3 F77=gfortran-mp-4.3 
LDFLAGS=-L/opt/local/lib LIBS=-lmetis

and successfully use backend("fltk") from within the binary.
