[Click] Problem in building and using RTPClassifier

[Eddie Kohler]

Roman,

The problem is not with argument parsing, it's with symbol truncation.  I may 
work on a fix long term.

Faraz,

The easiest fix is simply to take the unibo_qos package's elements and copy 
them into the click/elements/local directory.  Configure Click with 
--enable-local.  Then you should get those elements without having to load a 
separate package.
