Everything beyond dssp 2.0 uses a new syntax, which is not (yet) supported in gromacs. The new way of invoking dssp is described on the dssp webpage. Although undocumented, version 2.0 still accepts the old syntax, but NOT the -na flag, which is set by do_dssp unless you ask for syrface area calculations. Try to either install dssp 1.X or add e.g. the -a flag when executing do_dssp. The latter worked to my surprise.
There is a fix for this issue up for review that will (hopefully) go into gromacs 4.6. If you can't wait for that, it's pretty straightforward to modify how dssp is invoked in src/tools/do_dssp.c.
