I think the problem is rather that mkoctfile does not understand the option 
-framework Accelerate and does not pass it to the compiler/linker
Indeed, taking an example from your package, the following works for me:

mkoctfile -Wl,-framework -Wl,Accelerate slab09hd.cc \
              AB09HD.f TB01ID.f AB04MD.f TB01KD.f AB09HY.f \
              AB09IX.f MB03UD.f SB02MD.f AB09DD.f TB01LD.f \
              SB03OU.f MA02AD.f MB03QX.f select.f SB03OT.f \
              SB02MR.f SB02MS.f MB03QD.f SB02MU.f SB02MV.f \
              SB02MW.f MB04ND.f MB04OD.f MB03QY.f SB03OR.f \
              SB03OY.f SB04PX.f MB04NY.f MB04OY.f SB03OV.f

while this fals:

mkoctfile -framework Accelerate slab09hd.cc \
              AB09HD.f TB01ID.f AB04MD.f TB01KD.f AB09HY.f \
              AB09IX.f MB03UD.f SB02MD.f AB09DD.f TB01LD.f \
              SB03OU.f MA02AD.f MB03QX.f select.f SB03OT.f \
              SB02MR.f SB02MS.f MB03QD.f SB02MU.f SB02MV.f \
              SB02MW.f MB04ND.f MB04OD.f MB03QY.f SB03OR.f \
              SB03OY.f SB04PX.f MB04NY.f MB04OY.f SB03OV.f

I think you should configure Octave so that "mkoctfile -p BLAS_LIBS" returns 
"-Wl,-framework -Wl,Accelerate" 
rather than "-framework Accelerate". As you are using macports this should be 
done somewhere in your portfile
