According to the UTPure forums, UTPureRC6C is beta and may come in several versions depending on the beta "release" level. It is not ready for general consumption.
If you need it to get onto a server, you will need to talk to the server admin to get the specific version he/she is running.
IMHO, please wait until the official release to install this on any server (unless you are in the beta program). Having multiple versions that are probably incompatible floating around make life so confusing and problematic for the rest of us...
Bots?, Bots? I don't need no stinken' bots...
