gnome start errors after building gnome

[Huub]

Hi,

I built gnome, but when I change the .xinitrc according to the manual I 
get his:

_IceTransmkdir: ERROR: euid != 0,directory /tmp/.ICE-unix will not be 
created.
_IceTransSocketUNIXCreateListener: mkdir(/tmp/.ICE-unix) failed, errno = 2
_IceTransMakeAllCOTSServerListeners: failed to create listener for local

** (gnome-session:746): WARNING **: Cannot establish any listening sockets

It starts ok, but after the initial graphical screen it falls back to 
console. Anyone an idea?

Thanks,

Huub
