Just FYI: The program "rbpf-slam" suffers of a critical regression in mrpt 0.9.0 leading to crashing at start-up.
If you need that program, you can either go back to the older version of use the SVN HEAD, where the error was fixed a few days ago.
The release of 0.9.1 will be done ASAP mainly due to this bug, but will still take 1-2 weeks.
