title: Use waf to link boost on ubuntu
body: <p>I'm using waf to build a C++ project on ubuntu 13.10. I try conf.load(boost) in configuration function in wscript, but the result shows it cannot find boost in /lib64. I use apt-get to install libboost. It was installed on /usr/lib/x86_64-gnu-linux. It seems that waf cannot automatically search this directory. How to specify the location when load or check a library in waf.</p>
