Drop yum and use apt. At least apt will not just drop out but give a 
workable solution based on the packages you have installed and the 
possible solutions.

In fact I don't care about this breakage that much, because it should not 
be affecting you. Sadly, you are using yum.

Or you might be making yourself useful by trying to build audacity against 
the new environment (wxGTK) and let me know if you can make it work.

It is indeed sad that you cannot use yum anymore simply because there is a 
dependency issue. In fact, the most important reason for not mixing 
repositories is because yum dies on it, while other depsolvers give you 
solutions to make it work.

One might wonder why Red Hat choose the worst depsolver from the 
possibilities that existed at the time. And still hasn't improved the 

Of course the official word is: a repository should not break
My response is: yum should not break :)
