Thanks Jonathan for picking this issue up on the agenda. 

I guess the binary distro "-dev" packages are just workarrounds to the root 
cause of the problem. They split the conflicting compile parts out of the 
library to make it coinstallable on the build boxes. But on our side the build 
box is the end user box.

In addition to the information already provided by Jonathan. In Gentoo we have 
already packaged tier 1 & tier 2 live versions. In the wiki page you can see 
the conflicting files, which we hit already:

A search gives me the following result.

Maybe there are some false positives in it. If you need more information, i am 
happy to provide it.
