Well, I have applications that require 2.0, and others that require 2.0-0, so that's no solution for me.
I just removed any annoying package, as well as both libsdl's, and installed 2.0 again. Downloaded the current 2.0-0 via wget, and installed it via
After that, installing all the previously removed packages again...until now, everything seems fine

Don't know why it conflicts in /usr/lib/libSDL_ttf-2.0.so.0.6.3 and
/usr/lib/libSDL_ttf-2.0.so.0, or why there are two libsdl-ttf2 packages out there at all, but until now, as I said, everything works.

I also just got an upgrade of 2.0-0 which installed fine. Maybe this also renders my workaround unnecessary...who knows
