Hi I am trying to install rgbdslam as per the link //wiki.ros.org/rgbdslam. When I run 'rosmake rgbdslam_freiburg'

I get the error below:

IOError: [Errno socket error] [Errno 1] ssl.c:504: error:140770FC:SSL routines:SSL23GETSERVERHELLO:unknown protocol -------------------------}

[ rosmake ] Output from build of package octomap written to: [ rosmake ] /home/ap/.ros/rosmake/rosmakeoutput-20140312-152119/octomap/buildoutput.log [rosmake-11] Finished <<< octomap [FAIL] [ 0.37 seconds ]

[ rosmake ] Summary output to directory
[ rosmake ] /home/ap/.ros/rosmake/rosmake_output-20140312-152119

I tried deleting the octomapmsgs and octomapmapping packages and installing them again and running the 'rosmake rgbdslamfreiburg' but I get the same error above. I also tried making the packages before I run the 'rosmake rgbdslamfreiburg' command. The packages compile with no errors but I still get the error above when I run the mentioned command.

I'm using Ubuntu 12.04 LTS and ROS Fuerte. Help would be much appreciated. Thank you
