Emerging gnome-mount fails with a missing libgnome and doesn't DEPEND on it. gnome-mount does however depend on libgnomeui, which again depends on libgnome. So this might be redundant. checking pkg-config is at least version 0.9.0... yes checking for GNOME_MOUNT... configure: error: Package requirements (gnome-keyring-1 >= 0.4 libgnomeui-2.0 >= 2.1.5 dbus-glib-1 >= 0.31 hal-storage >= 0.5.7 gtk+-2.0 >= 2.8.0) were not met: Package libgnome-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `libgnome-2.0.pc' to the PKG_CONFIG_PATH environment variable Package 'libgnome-2.0', required by 'libgnomeui', not found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GNOME_MOUNT_CFLAGS and GNOME_MOUNT_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.
Can you post the output of emerge -pv gnome-mount please? It already has a dependency on libgnomeui.

see if you have libgnome and libgnomeui 2.16 since libgnomeui depends of libgnome. maybe it's some version mismatch around here. Please try rebuild again and test. Reopen if you have more news about this.
