GNOME Do 0.8.3 dependancy on gnome-desktop-sharp vague

GNOME Do doesn't report exactly what versions of gnome-desktop-sharp it wants, but parts crash with the following error if 2.26 isn't installed:
[Error 16:51:52.908] Could not load desktop item: libgnome-desktop-2.so.7

Additionally, if I try to open the Preferences window, the following error occurs:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.DllNotFoundException: libgnome-desktop-2.so.7

This is running GNOME Do 0.8.3.1 on Gentoo 64-bit with gnome-desktop-sharp-2.24.0-r10 installed (r10 referring to the number of Gentoo-specific revisions, I believe). If I use gnome-desktop-sharp-2.26 GNOME Do is fine, and all errors vanish.

The GNOME Do configure script needs to be updated, or code needs to be patched, so that this error does not occur anymore. If that means bumping the requirement for gnome-desktop-sharp-2.26, that's fine with me. It just needs to be documented.

The Gentoo-specific bug will be attached for reference (if I can make it work). Any additional information required will be given promptly; finals just ended for me, so I have quite a bit of time all of a sudden. :)
