Hi, 

 After checking out a copy of mrpt_common, mrpt_hwdrivers, and mrpt_slam
I tried to build mrpt_common and received errors.  See below.  I get
similar errors when I try to rosmake mrpt_slam.  However, mrpt_hwdrivers
appears to build OK.  Any ideas?. 

Note: tried to "report bugs" link on
http://www.ros.org/wiki/mrpt_common# but link was bad - "Environment not
found" on an otherwise empty page.
