Bugzilla Bug 115944

I emerged gnome-2.12.1
The portage took care of all the dependencies except
glib which should be >=2.8.0

FROM COMPILATION:
checking for i386-pc-linux-gnu-pkg-config... (cached) /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for GNOME_DESKTOP... configure: error: Package requirements
(gdk-pixbuf-2.0 >= 2.4.0 gtk+-2.0 >= 2.4.0 glib-2.0 >= 2.8.0 libgnomeui-2.0 >=
2.6.0 gnome-vfs-2.0 >= 2.0.0 libstartup-notification-1.0) were not met.
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively you may set the GNOME_DESKTOP_CFLAGS and GNOME_DESKTOP_LIBS
environment variables
to avoid the need to call pkg-config. See the pkg-config man page for
more details.

!!! Please attach the config.log to your bug report:

Fixed.  Sorry about that.
