To ensure that if something ends up loading libcalendaring into the kontact 
process that everything still works.

All libs in Debian go to a shared install directory, /usr/lib (or 
/usr/lib/TRIPLET ), so different destinations are not good enough. That also 
implies different SONAME's for the libraries.

What applications would have to use it interchangeable ? I'd expect the kolab 
server people to just use the libcalendaring versions, while the kontact users 
would use the kdepimlibs versions.

I want to ensure that neither of us gets to debug weird crashes if both 
libraries are loaded into the same application.
