Upstream commented on the Ubuntu bug (https://bugs.launchpad.net/ubuntu/+source/crystalspace/+bug/903121). I'm copying it here as it is relevant:
"Hi, Thank you for raising this issue. The crystalspace 1.4.x series will not be updated to support the latest cegui 0.7.5. We have a 2.0beta1 now released which does support the latest cegui and does build with both debian and ubuntu (1). The final release for crystalspace 2.0 is scheduled for Feb 2012. Timed specifically to be ready prior to major distributions 6 month releases. (1) New simple 'example' scripts for debian and ubuntu builds for the 2.0 series, now reside in the archive. Look under in the folder 'scripts/packaging/deb'. Regards Phil Wyett - CS Dev Team and Release Manager" -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
