I have the same trouble trying to install the XMLDocument product. My guess is that somebody upgraded to a glibc2.1 system (e.g., RH 6.0) and built the Linux binaries (the .so files) there.
We recently had to rebuild the binaries for the linux dist. (for all of them actually, to make sure that _localemodule was included by default). At the time, I didn't realize that the dev. machine had been "upgraded" to glibc2.1 :( The upshot is that the linux binary currently on the website is currently only usable for RH 6.0 users. If you _must_ upgrade before Monday and you are on 5.x, you will want to get the source distribution and build it yourself. Monday we will get the binaries for the linux binary dist. rebuilt on a 5.x machine and do some testing. Then I'll update the release on the site and we'll hopefully have a binary that's good for both 5.x and 6.x.
