It would be fairly expensive to do a complete directory scan to find
the highest version (I have 2000+ files in /usr/lib, for example).
The solution is to use the dllmap mechanism in the mono config file,
adding an entry like:
	<dllmap dll="gnome" target="libgnome.so.32" />

(if "gnone" is the name used in the DllImport atribute).
Note: libgnome.so.32 doesn't include the minor library version, so that
you don't need to deal with changing the config file unless libgnome
changes in a backward-incompatible way: in that case the Gnome# code
would need to be changed as well anyway.
