So I am trying to install Pyv8 by following instruction from https://andrewwilkinson.wordpress.com/2012/01/23/integrating-python-and-javascript-with-pyv8/
I followed the instructions from this link - http://ubuntuforums.org/showthread.php?t=1480282#post_11247864
and installed the libboost_thread package which solved the problem. Thank you https://stackoverflow.com/users/440558/joachim-pileborg
