Thomas, are you asking how to use the "-bundles" flag?

If so, I assume you know it is a linker option. I haven't tried to  
compile any oct-files yet. However, for Matlab, I created mex-files  
using a makefile. The link phase is

gfortran -funroll-loops -ftree-vectorize -O5 -Wl,-flat_namespace - 
undefined suppress -bundle  -Wl,-exported_symbols_list,/Applications/ 
MATLAB_R2007b/extern/lib/maci/fexport.map -o my_mex_function.mexmaci  
my_object_code.o /Applications/MATLAB_R2007b/extern/lib/maci/ 
version4.o -L/Applications/MATLAB_R2007b/bin/maci -lmx -lmex -lmat -lm

I hope that is some help.
