I was trying to compile tomboy-0.4.1 when I ran into this: mcs -out:Tomboy.exe -debug -define:DEBUG -unsafe -target:exe -define:ENABLE_DBUS -define:ENABLE_GTKSPELL -define:FIXED_GTKSPELL Tomboy.cs Applet.cs Logger.cs Note.cs NoteManager.cs NoteWindow.cs NoteBuffer.cs NoteTag.cs PluginManager.cs Preferences.cs RecentChanges.cs Search.cs Tray.cs Trie.cs Undo.cs Utils.cs Watchers.cs XKeybinder.cs panelapplet/BonoboUIVerb.cs panelapplet/ChangeBackgroundHandler.cs panelapplet/ChangeSizeHandler.cs panelapplet/GnomeSharp.PanelAppletFactoryCallbackNative.cs panelapplet/MoveFocusOutOfAppletHandler.cs panelapplet/ObjectManager.cs panelapplet/PanelAppletBackgroundType.cs panelapplet/PanelApplet.cs panelapplet/PanelAppletFactoryCallback.cs panelapplet/PanelAppletFactory.cs panelapplet/PanelAppletFlags.cs dbus-sharp/Arguments.cs dbus-sharp/Array.cs dbus-sharp/Boolean.cs dbus-sharp/Bus.cs dbus-sharp/BusDriver.cs dbus-sharp/Byte.cs dbus-sharp/Connection.cs dbus-sharp/DBusException.cs dbus-sharp/Double.cs dbus-sharp/Error.cs dbus-sharp/ErrorMessage.cs dbus-sharp/Handler.cs dbus-sharp/IDBusType.cs dbus-sharp/Int16.cs dbus-sharp/Int32.cs dbus-sharp/Int64.cs dbus-sharp/InterfaceAttribute.cs dbus-sharp/InterfaceProxy.cs dbus-sharp/Introspector.cs dbus-sharp/Message.cs dbus-sharp/MethodAttribute.cs dbus-sharp/MethodCall.cs dbus-sharp/MethodReturn.cs dbus-sharp/ObjectPath.cs dbus-sharp/ProxyBuilder.cs dbus-sharp/Server.cs dbus-sharp/Service.cs dbus-sharp/SignalAttribute.cs dbus-sharp/Signal.cs dbus-sharp/String.cs dbus-sharp/UInt16.cs dbus-sharp/UInt32.cs dbus-sharp/UInt64.cs RemoteControl.cs RemoteControlProxy.cs Defines.cs -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/pango-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/atk-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gdk-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gtk-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/glib-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gnome-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/art-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gnome-vfs-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gconf-sharp.dll -r:/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gconf-sharp-peditors.dll -r:Mono.Posix -resource:../data/GNOME_TomboyApplet.xml,GNOME_TomboyApplet.xml -resource:../data/DefaultPlugins.desktop,DefaultPlugins.desktop -resource:../data/images/tomboy.png,tomboy.png -resource:../data/images/gnome-searchtool.png,gnome-searchtool.png error CS0006: Cannot find assembly `/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gnome-sharp.dll' Log: error CS0006: Cannot find assembly `/usr/lib/pkgconfig/../../lib/mono/gtk-sharp-2.0/gnome-vfs-sharp.dll' Solution: Tomboy uses "pkg-config --libs" to find the location of these dlls. gnome-sharp-2.0.pc.in (2.16) and gnome-vfs-sharp-2.0.pc (2.16) in their respective packages both have incorrect paths: Libs: -r:${libdir}/mono/gtk-sharp-2.0/gnome-sharp.dll Libs: -r:${libdir}/mono/gtk-sharp-2.0/gnome-vfs-sharp.dll If I change "gtk-sharp" to "gnome-sharp", tomboy compiles and runs. Same story with beagle. I'm not sure if the .pc files or the .pc.in source files or whatever should be patched, but you get the idea.
Please see https://bugs.gentoo.org/show_bug.cgi?id=146659#c1, it seems you somehow have a borked gnome-sharp-2.16.0 install. Those paths are in fact right, but some things got installed to the wrong spot somehow.
Marking INVALID, see bug #146659
