example: Gentoo Linux is heavily dependent on Python and I recently
emerged in several packages. I don't remember the exact details, but

upstream packages required two different linkages, and the wrapping
Python modules were thus incompatible. I basically had to decide
which one I cared about most and delete the other to resolve the
conflict. The problem was confusing the hell out of several
Gentooers until we tracked down all the resources and figured out the
