Well, that was a stupid mistake. I double-checked that everything containing the phrase "kde" was deleted from my /usr directory to ensure that my old KDE3 installation didn't bother the KDE4 stuff. Unfortunately, "kwin" doesn't contain "kde".
As a side note, I just bombed my /usr/include directory trying to fix the thing but hey, at least I know what is wrong now. And I learned that typing any rm instruction when way too tired is generally a bad thing to do while making backups before trying to fix stuff is pretty awesome. Learned it the hard way, but finally learned it. -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
