Optimization and DFT-D3 energy calculation in GamessFireFly version 8.1.1

My input was

$CONTRL SCFTYP=RHF DFTTYP=B2PLYP DFTD=.T. d5=.T. RUNTYP=OPTIMIZE$END
$DFTD VERSN=3$END
$SYSTEM TIMLIM=3000 MEMORY=30000000$END
$BASIS EXTFIL=.T. GBASIS=acc-pvdz$END
$STATPT HSSEND=.T. NPRT=-2$END
$FORCE NVIB=2 VIBSIZ=0.005$END
$DATA H2O C1 O 8.0 -3.46278 2.54045 0. H 1.0 -2.50278 2.54045 0. H 1.0 -3.78324 3.44539 0.$END


I am getting the following error:
FATAL ERROR: DFTTYP = B2PLYP DOES NOT YET HAVE GRADIENTS PROGRAMMED.

So is it not possible to perform optimization with this functional?

In original GAMESS-US code there are no analytic gradients for "double hybrids" and it looks like it is true for Firefly as well. You can use numerical gradients by adding NUMDER=.T. in \$CONTRL section. See this for details.
