hello, newb needing a little help, installing compiz 0.8.4 via SBo, Slackware 13.0 x86_64
any advice would be greatly appreciated.

Code:

decorator.cpp: In member function 'bool KWD::Decorator::enableDecorations(Time)':
decorator.cpp:212: error: cannot allocate an object of abstract type 'KWD::Window'
