garnome 0.21 on Red Hat 8.0 cannot open display

[Nacho <nachoge terra es>]

Hi there,

I using Red Hat 8.0 fully updated

i build genome using garnome 0.21 and it seems to be ok but when I try
to run the startup script (from garnome site)

---------------------------------------------
#!/bin/sh
GARNOME=$HOME/garnome

PATH=$GARNOME/bin:$PATH
LD_LIBRARY_PATH=$GARNOME/lib:$LD_LIBRARY_PATH
PYTHONPATH=$GARNOME/lib/python2.2/site-packages
PKG_CONFIG_PATH=$GARNOME/lib/pkgconfig:/usr/lib/pkgconfig
GDK_USE_XFT=1

export PATH LD_LIBRARY_PATH PYTHONPATH PKG_CONFIG_PATH GDK_USE_XFT

exec $GARNOME/bin/gnome-session

----------------------------------------

appears a GTK Warning message

(gnome-session:1450): Gtk-WARNING **: cannot open display:

I try to export 

DISPLAY=localhsot:0.0

  it takes a while but continues the same message

Thanks in Advance

Nacho
