Apparently further from maemo mce support that I thought.

osso-systemui failing at the moment. The Cordia based libhildon has removed some HildonBanner related code for hildon_banner_show_information and hildon_banner_set_timeout. The later should still be achievable via setting property, but the first requires code to be reinstated or changed.

Several other packages (osso-systemui-powerkeymenu, osso-systemui-tklock to name but 2) require GTK3 port.

Every time you think your getting closer you find more packages, depending on more packages.

osso-systemui-tklock requires libalarm-dev (have sources) which requires libtime-dev (libtime0 is AFAIK another blob).

Finished setting up Stretch container this morning and pulled in a few repos to start building whilst I was out. It's not as straight forward building packages as it is for Jessie, but that has been my target environment for a while.
