#dh_shlibdeps has a problem finding which package some of the Haskell
#libraries come from, even though dpkg-query -S has no problem finding them.
#But the gf executable is statically linked against the Haskell libraries, so
#it will work even if these shared libraries aren't installed. But there will
#be a problem if other shared libraries are missing (.e.g. libtinfo, libgmp),
#so we need a better solution than simply ignoring all dependency problems...
