I don't test, but like a following?
But current databases/gdbm does not install gdbm_compat, so can't use as ndbm.
(I might ask on somewhere at sometime that gdbm_compat should be added as 
option for gdbm or separate package...)

.if exists(/usr/include/ndbm.h)
NDBM_TYPE=      builtin
.else
CHECK_BUILTIN.db1:=     yes
.  include "../../mk/db1.builtin.mk"
CHECK_BUILTIN.db1:=     no
.  if !empty(BUILTIN_FOUND.db1:M[yY][eE][sS])
NDBM_TYPE=      db1
.  else
NDBM_TYPE=      gdbm
.  endif
.endif
