[Click] Problem in building and using RTPClassifier

[Cliff Frey]

I believe that this is telling you the error:
  !!! Your kernel was compiled with CONFIG_MODVERSIONS.
  !!! Click packages are often incompatible with CONFIG_MODVERSIONS.
  !!! You may need to recompile your kernel and rebuild Click.

Specifically, click cannot be loaded into recent linux kernels that
are compiled with CONFIG_MODVERSIONS, because click ends up using
symbols that are too long.  There was a recent message about this to
the click mailing list.
