teleop_base compile errors from boost.

edit

I am working through the Stage Simulating One Robot tutorial, but am having trouble compiling teleop_base. I had to change the default directories in several places, and am now stuck with errors in the cmake files related to boost (at least, this is what I gather from the output). Here is the end of the results from running "rosmake teleop_base":

Any help as to where to start fixing this problem would be welcome. I'm not even quite sure where to look/what the errors might be in relation to. I'm new to ROS and Stage. Thank you in advance.
