RGBDSLAM fails rosmake and rosdep in fuerte

edit

I am trying to use rgbdslam in fuerte on 12.04 LTS. I was able to overcome some problems, like the dependency on eigen by following these directions.

Now I am having a different error.

bowser@bowser-ros:~/fuerte_workspace$ rosdep install rgbdslam
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
rgbdslam: Cannot locate rosdep definition for [gl2ps]

I tried to install the packages as described in the link, but they were already up to date. Rosmake also fails with following error:

    /usr/bin/ld: cannot find -lGLEW
      /usr/bin/ld: cannot find -lIL
      collect2: ld returned 1 exit status
      make[1]: *** [siftgpu] Error 1
      make[1]: Leaving directory `/home/bowser/fuerte_workspace/rgbdslam/external/siftgpu/linux'

      ------------------------------------------------------------------

      CMake Error at CMakeLists.txt:103 (MESSAGE):
        SiftGPU cannot be compiled.  Returned: 2



  -- Configuring incomplete, errors occurred!

the full build_output.log is here.

I am trying to learn more about SiftGPU to figure out what problem could be, but I'm not really sure where to look right now, or if siftgpu itself is the problem, or if I'm missing some other dependency.
