无法安装gnome

我一步一步地按照handbook安装gnome,之后出现了如下信息：
(==)Log file:"/var/log/Xorg.0.log"
(==)Using config file:/etc/X11/xorg.conf
(II)Module already built_in:
/home/user/.xinitrc:exec:gnome-session:not found

and:
waiting for X server to shut down FreeFontPath:FPE "/usr/share/fonts/misc/" refcount is 2,should be 1;fixing.

步骤：
(1)USE="-qt3 -qt4 -arts -kde X dbus gtk gnome hal avahi"

(2)# echo "gnome-base/gnome-session branding" >> /etc/portage/package.use

(3)# emerge gnome

(4)# env-update && source /etc/profile

(5)# emerge gamin

(6)# /etc/init.d/hald start
//这里它提示hald不存在，为什么？？？

# rc-update add hald default

(7)# /etc/init.d/dbus start

# rc-update add dbus default

(8)# /etc/init.d/avahi-dnsconfd start

# rc-update add avahi-dnsconfd default

(9)$ echo "exec gnome-session" > ~/.xinitrc

(10)$ startx

我怀疑我emerge 的时候出现错误了，于是：

出现的信息我看不太明白，不知道如何解决，我又重新：
#emerge gnome，
又出现了如下的信息:
ebuild.sh,line 49:Called src_compile
environment,line 608:Called gnome2_syc_compile
environment,line 543:Called gnome2_src_configure
ebuild.sh,line 529:Called die

The specific snippet of code:
die "econf failed"
The die message:
econf failed.

谁知道如何解决啊？？
