I had the same problem and didn't fix it yet. I went to the Word Perfect web site a while ago and if you click around you will find a Linux support page with a newsgroup. In reading the postings you will find that several other people have the same problem.
My recollection is that "the experts" said we need to have two different versions of glibc at the same time, separated so as to not mess up the rest of the system. Since I'm new to Debian it seemed like a good way to break my package system. Just thought I would pass that along. They may have an answer over there by now. Good luck, Joe Bouchard
