...and for Metamod:

           META_ERROR("dll: Unrecognized game: %s", GameDLL.name);
           // meta_errno should be already set in lookup_game()
           return(mFALSE);
     }

+    if (access(GameDLL.real_pathname, 0) == -1) {

+       unsigned char *filebuf;

+       i = strlen(GameDLL.real_pathname) - 1;

     // open the game DLL
     if(!(GameDLL.handle=DLOPEN(GameDLL.pathname))) {
          META_ERROR("dll: Couldn't load game DLL %s: %s", GameDLL.pathname, DLERROR());
          RETURN_ERRNO(mFALSE, ME_DLOPEN);

I'll send this to Will Day and hope he can fix this in next version.
