Cannot run gnome

["Surya Kiran Gullapalli" <suryakiran gullapalli gmail com>]

Hi,
I've compiled gnome desktop using garnome-2.15.4. But when i try to run gnome-session, it fails saying it cannot run gnome-sesion due to some error in dbus. My xinitrc file is given below. What am i doing wrong?
==============================
!/usr/bin/env bash

GARNOME="$HOME/Packages/Desktop-Packages/Gnome-2.15.4"

export PATH=$GARNOME/bin:$PATH
export LD_LIBRARY_PATH=$GARNOME/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=$GARNOME/lib/pkgconfig:$LD_LIBRARY_PATH

PYTHONPATH=$GARNOME/lib/python2.4/site-packages
XDG_DATA_DIRS=$GARNOME/share
XDG_CONFIG_DIRS=$GARNOME/etc/xdg
GDK_USE_XFT=1

export PYTHONPATH GDK_USE_XFT 
export XDG_DATA_DIRS XDG_CONFIG_DIRS 

exec $GARNOME/bin/gnome-session
=============================
