Problem compiling modular_cloud_matcher

edit

Hi, I was installing modular_cloud_matcher following instructions on this page: modular_cloud_matcher. However there's an error which is as below:

[rosmake-0] Starting >>> libnabo [ make ]

Did I do something wrong or I forgot something important? I'm using Electric on Maverick. Thanks for answering!
