The latter is true.

It is a problem, because it depends now on the installation order. Usual 
RPMs produce the symlinks in their postinstall script to allow several 
versions of the lib to be installed (well, some others do not, but those are 
broken anyway). 

This means the correct functioning depends on the order of installation. 
Given that people start to experiment with their installation as sonn as 
something doesn't work, this is quite likely to be a problem.
