I've tried to upgrade an existing Raspbian OS to version 20130525 according to the comments in the original announcement and seem to have succeeded as it shows:
OS: Linux, 3.6.11+, #456 PREEMPT Mon May 20 17:42:15 BST 2013, armv6l
Then I added weston according to instruction in comment http://www.raspberrypi.org/archives/4128#comment-79401
but when I try to start it a fatal error is thrown

I also got below error during preceeding step 'sudo apt-get -y update'

but 'sudo apt-get install weston' claims the version is up-to-date.

weston is already the newest version.

Could this be the root cause?
How would I overcome it?
