A search for 'UnofficialVersion' in your source code did not find
anything.

Here is the relevant part from MLPov:

      /*ML: version_patch*/
     #ifdef MLUNOFFICIAL
     /* parse unofficial version */
     Get_Token();
     if (pov_stricmp(Token.Token_String,"mlpov") != 0)
     {
       Error("This version only recognizes #version unofficial mlpov\n"); 
     }
     opts.Unofficial_Version = (int)(Parse_Float() * 100 + 0.5);;
     Parse_Semi_Colon(false);
     if (opts.Unofficial_Version > UNOFFICIAL_VERSION_NUMBER)
     {
        Error("Your scene file requires MLPOV version %g or later!\n",
(DBL)(opts.Unofficial_Version / 100.0));
     }

     [...]

I think this is fairly simple (compared to megapov) and you can also quite
easily add support for multiple unofficial version strings (in case
several patches are merged and old scene files should render without
changes).

The 'Unofficial_Version_Blocking()' function seems a good idea though.
