Apparently, Karolina's KDE3.1RC5 packages came with its own version of SDL, which conflicted with Sid's SDL packages and removed them. Unfortunately, there is no libsdl-dev package that has the SDL headers, so my development work, which requires SDL has ground to a halt.
Are there any easy workarounds to this? If I try installing the Sid SDL packages, dselect asks me to remove every KDE3.1 package on my system. Of course, these kinds of issues wouldn't happen if KDE3 was in unstable months ago like it should, but I'm not bitter...
