[Distutils] easy_install problem

[Nitin Dhiman]

I tried and following is the output.

nitin at nitin-desktop:/opt/ros/diamondback/ros$ sudo easy_install -vv -U
rosinstall vcstools
Searching for rosinstall

Just a wild thought, could it be because that i can not access
internet from shell while i could do so from browser. May be some
settings which are not available to shell from gnome. This is how my
network is currently configured:

$ cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
	address 192.20.16.45
	gateway 192.20.16.1
	netmask 255.255.255.0
