Comment (by fbissey):

 I think it is time for me to crash the party. First I notice that you made
 `gap_packages` and `database_gap` depend on `libgap`. Only `gap` is
 needed.

 I think it is time for me to point out that `grape` includes an old
 version of `nauty` and can use either `nauty` (now a standard package) or
 `bliss` (now an optional package). Look at `GRAPE_DREADNAUT_EXE` in
 `grape/lib/grape.g` (and the variable `GRAPE_NAUTY` and `GRAPE_BLISS_EXE`
 in the same file if you are curious).
 I recommend removal of the `configure` and other makefiles in `spkg-src`.
 The only point of that bit in the `grape` package is to build the
 `dreadnaut` executable from `nauty`.

 I am OK if you want to spin that as a separate ticket.
