cannot install Selenium2Library properly #163

Win7 64 bit
i installed the package both with pip and easy_install, and both have the same result.
on the cmd line in a DOS window, in Python, i'm able to import Selenium2Library without errors,
but when i try to run an ant script from within Eclipse , starting org.robotframework.RobotFramework via a java task (which obliges me to set my classpath myself within the ant-script),
i have the below issue.
I could already get rid of the error "cannot find module decorator" (allthough also installed via easy_install) by copying the decorator directory into my project, and adding this project directory in my ant java classpath.
However, the below error i cannot get rid of because i don't understand the problem.

When i go the keywordgroup file in Eclipse, i get the warning "assignment to reserved build in symbol dict.
