I set up a maemo environment on my ubuntu box today. It was quite easy as they provide a good documentation and an easy installation script. There are some things that do not work perfectly yet but I think they can be fixed.
Currently trying to set up glom put I have problems to connect to the database. Seems like libgda got installed without support for postgresql but I am not sure yet. Retrying with jhbuild now...
No volunteers for gnome-build, yet! Applied patch from Günther Brammer (thanks!) to fix a parsing bug with "+=".
