errors compiling rgbdslam, g2o errors about cholmod

edit

Hello! I am trying to build rgbdslam and not having much luck. I am using Ubuntu 11.10 64 bit. I have latest ros electric installed. I pulled the latest rgbdslam (from http://www.informatik.uni-freiburg.de/~endres/rgbdslam/rgbdslam.tgz). I also pulled g2o from svn. g2o builds fine and all dependencies pulled down and built when I did a "rosmake --rosdep-install rgbdslam". Initially I was getting some errors related to undefined references and it appeared that the g2o libs were not being linked in. So I added all the libg2o* libraries to rgbdslam's CMakeLists.txt. This got me further but some errors remain and I'm not sure where these dependencies are.

Here is an excerpt from my buildfailures-with-context.txt:
