I have been getting to grips with OpenEmbedded and in particular bitbake. When everything works it is a great system and makes building packages for different platforms a piece of cake. I created a bitbake recipe to automatically checkout from CVS and build an ipk.
This can be installed on the Neo as follows:
opkg install https://projects.openmoko.org/frs/download.php/167/thumbtribes_0.4-r0_armv4t.ipk
