Thank you very much for your reply, Ben. I have tried out some oct-files like

mkoctfile -Wl,-framework -Wl,vecLib \
          slag08bd.cc \
          AG08BD.f AG08BY.f TG01AD.f TB01XD.f MA02CD.f \
          TG01FD.f MA02BD.f MB03OY.f

(the example above is the second mkoctfile call in src/makefile_zero.m)

and it worked fine when I called mkoctfile from bash. However, running 
mkoctfile inside octave leads to

octave:1> cd (fileparts (which ("makefile_zero")))
octave:2> mkoctfile -Wl,-framework -Wl,vecLib \
>           slag08bd.cc \
>           AG08BD.f AG08BY.f TG01AD.f TB01XD.f MA02CD.f \
>           TG01FD.f MA02BD.f MB03OY.f
usage: basename string [suffix]
       basename [-a] [-s suffix] string [...]
error: `framework' undefined near line 2 column 16
octave:2> 

which means that makefile_*.m and (just guessing) pkg install don't work.

There seems to be another problem:
Since googling framework veclib returns only Macintosh-related hits, it looks 
like a mac-specific option. Therefore, adding "-Wl,-framework -Wl,vecLib" to 
src/Makefile would break installation on other platforms (unless they ignore 
unknown options, which is IMHO unlikely).

BTW: Where did you find those options? My help mkoctfile doesn't mention them, 
neither does
/scripts/miscellaneous/mkoctfile.m
on hg.savannah.gnu.org


Thanks again and best regards,
Lukas
