A lot of compat libs work like that, the runtime packages with the versioned 
so-s are parallel installable, the -devel packages conflict.

This is also what upstream KDE is planning to deliver.

Guess why I hate them too.
There's the possibility of switching between the packages or of using a mock 
chroot, but that sucks.

Same as above.

Sure I could patch the heck out of KDE to install the symlinks 
into /usr/lib/kde[34], rename conflicting binaries etc., but then we'd probably 
have to patch the heck out of all applications building against it. KDE doesn't 
use pkg-config, and kde-config has no --libs option where you can easily add 
a -L foo option. And this doesn't even cover stuff like kconfig_compiler.

Or we could install one of the 2 KDE versions into a custom prefix 
like /opt/kde3 or /opt/kde4, and in fact this is what my current kde*4 packages  
do, but then good bye FHS.

Rex Dieter, I think you have the best contacts upstream, could you please take 
this up with them?

But I'm not sure about the "every other distribution" part. OpenSUSE had KDE 3 
in /opt/kde3, so they're not affected by most of this, and the others probably 
just have the -devel packages conflict.
