WARNING: could not load plugin 'crystalspace.kernel.vfs'
ERROR: Couldn't setup vfs! Is Crystal Space setup correctly?
 * This likely means that the plugins could not be found. 
 If you're a user: Check the working directory the application starts from -
  usually, it is the same as the directory with the executable.
  If in doubt, contact the vendor.
 If you're a developer: Check if the CRYSTAL environment var points to the
  correct location - usually the directory CS was built in.
  You can also use the '--verbose' command line switch to troubleshoot
  where CS looks for plugins.
