Sorry, that was silly: I forgot to include OSG in that command; since
the 'openscenegraph' symlink I had in the “dnc-managed” dir pointed to
an osg repo where the 'next' branch was checked out, the build used
that (precisely, 51b991fe6). I've now rerun the build with:

  download_and_compile.sh --cleanup -s -pn -j$(nproc) -GNinja OSG SIMGEAR FGFS DATA

With this, I obtain errors that look quite like yours (bo23):
