That seems like the correct analysis of the problem to me, too. I've
had to patch some of my own packages to deal with similar issues on 10.9.
is_void() doesn't seem to be exported, so as a workaround (I'm still
building up the dependencies so you might still run into a different
error), you might try the editing
/sw/fink/dists/stable/main/finkinfo/sci/grass64.info and change
PatchScript: sed 's|@PREFIX@|%p|g' < %{PatchFile} | patch -p1
to
PatchScript: <<
sed 's|@PREFIX@|%p|g' < %{PatchFile} | patch -p1
sed -i.bak 's|is_void|grass_is_void|g' raster/r.terraflow/direction.cc
raster/r.terraflow/nodata.cc raster/r.terraflow/nodata.h
<<
(the second sed command should be on one line, in case my mailer ruins it).
