The error is:
NameError: global name 'Carnage' is not defined

Answer 1

The cause of your error is that Carnage has not been defined. Maybe you forgot to import a library which provides Carnage?
Also, your code as posted is incorrectly indented, which is a syntax error.
Update: Apparently you took this code from http://github.com/Ejz/Common/tree/master/carnage-bot . Reading that source, it looks like the line
aCarnage = Carnage('YourNick', 'YourPass', 'arkaim.carnage.ru', 'cp1251', agent)
Should be
aCarnage = CarnageBot('YourNick', 'YourPass', 'arkaim.carnage.ru', 'cp1251', agent)
Because the methods called on aCarnage are defined further down the file for class CarnageBot.
