I have install Anaconda 2.0.1 on KDE desktop. When I run python and would see all modules installed, I have this message "Cannot mix incompatible Qt library (version 0x40801) with this library (version 0x40805)",

Can I fix the problem if I unintall Qt library (version 0x40801)? 
How I do that? 

Or if someone have another suggestion,please help me, 

Thx very much
