Heya,

Ideally you should /not/ have KDevelop libraries or plugins installed into a 
prefix which is automatically picked up by the runtime linker [1]; so, for 
instance, "/usr/lib".

Best is to install KDevelop solely into distinct prefixes, think of $HOME/opt/
kdevelop-53, $HOME/opt/kdevelop-54, etc.. This probably circumvents the 
problem(s) you're seeing.
