Code review comment for lp:~dobey/ubuntuone-client/support-older-vala

This should build successfully on Lucid, Maverick, or Natty. To test, make sure libsyncdaemon-1.0-dev is not already installed if you are on Natty, as the nightlies package already contains the libsyncdaemon-1.0.vapi, so the build may still succeed even if the local .vapi has not been generated, as valac will look at the installed one.
