Easy_install not working in Hue 4.6 when installing few of python packages

Hi Romain,

Earlier The Hue bundle was building properly , there is no change in server package installation.
While we are building Hue bundle now we are getting error related to python packages.It seems easy_install command is not working. Can you please suggest required solution here.
Please share the solution for Hue 4.6 version.
