That certainly is what I suspect.

~/install/bin/weston is setuid and owner and group are set to root.

Also ~/install/libexec/ and ~/install/libexec/weston-desktop-shell and 
~/install/libexec/weston-tablet-shell have owner and group set to root, 
which is a bit annoying but probably a side-effect of doing "sudo make 
install" in weston.

When weston is running, I guess these are the sockets, they are set as 
follows:

ls -l /tmp
srwxr-xr-x 1 root    spitzak       0 2012-03-14 08:17 wayland-0
-rw-r----- 1 root    spitzak       0 2012-03-14 08:17 wayland-0.lock

There is also a file with the same timestamp in there:

-rw-r--r-- 1 spitzak spitzak    1670 2012-03-14 08:17 fileIFXN7F

I also tried running wayland outside X, although X was running. It 
messed up the screen and produced the following output and then exited:

compositor: using new vt /dev/tty8
nvfx_screen_get_param:103 -  Warning: unknown PIPE_CAP 57

The system was locked until I typed Alt+F7 to get X display back, then 
Alt+F1 which put me back into the terminal with this output and I could 
type again.
