No such file or directory: 'ubuntuone.override' when building sourcecode

When building the sourcecode on a 'foo' directory, I'm getting:

nessita@dali:~/canonical/libubutuone/trunk$ mkdir foo; cd foo/
nessita@dali:~/canonical/libubutuone/trunk/foo$ ../autogen.sh --enable-debug && make && sn -T bindings/mono/ubuntuone-sharp.dll
/usr/bin/gnome-autogen.sh
