Hi Manish,
Thanks for posting the complete output. It would be good to know which
distro version you're running. Please see comments below.

You might want to fix these warnings.

It seems strange that it's looking here when you've installed to ~/install/.

This string means the driver is using software routines for rendering.

This error looks suspicious.

I don't have any definitive answers but you'll want to get 3D working in
any event. You can check your /var/log/Xorg.0.log file,
http://nouveau.freedesktop.org/wiki/FeatureMatrix or ask in #nouveau. So
far as the general error messages, something seems strange with your system
or installation that's confusing weston or, that's triggering a bug. I'd
recommend getting hardware acceleration working first, then proceed from
there.
