[Vala] What is required to make vtg (vala tools for gedit) under Ubuntu 11.10 ?

[Serge Hulne <serge hulne gmail com>]

The gedit plugin vtg works under Ubuntu 11.04, but not under Ubuntu 11.10.

I guess it could be because the plugin API for gedit has changed ?

It compiles, but does not register under the list of plugins of gedit after
installation.

Has anybody managed to get it to work ?
If yes, I would be glad to have the recipe !

Thanks,
Serge.
