What version of glib do you have installed? Also, are you able to reproduce this with libgnomeui-2.14.1?
The affected system has the following glib-packages installed: [I--] [ ] dev-libs/glib-1.2.10-r5 (1) [I--] [ ~] dev-libs/glib-2.10.1-r1 (2) The timestamps suggest, that these packages where installed before the installation of any gnome-2.14-package. I fear that I'm unable to try to reproduce that under comparable condintions with gnome-base/libgnomeui-2.14.1, as I have no backup of the original sys-devel/automake-1.9.4, which is also not in portage anymore.
libgnomeui-2.14.0 doesn't really need >=automake-1.9. Anyway, this should be fixed in libgnomeui-2.14.1.ebuild.
