OpenIndiana Distribution

on a headless system I installed xvnc but startup of vncserver ends with error:

Could not start Xvnc.

Could not setppriv() PRIV_PERMITTED_XSERVTransmkdir: ERROR: euid != 0,directory /tmp/.X11-unix will not be created.

vncserver starts if is installed also:

x11/keyboard/data-xkb
x11/keyboard/xkbcomp

so xvnc depends on and should also install this two packages.
