Sorry all folks for the trouble - I updated the installation notes in the first post just now... I've had these packages installed for ages now and I just plain forgot about the special Maemo stuff...

mypaint-0.8.2 HOWTO until aapo includes the dependencies in the package in extras-devel:

enable extras-devel

as root
apt-get install mypaint mypaint-data python-support python-hildon python-osso

cd /usr/lib/
ln -s libblas.so.3gf libblas.so
ln -s liblapack.so.3gf.0 liblapack.so

should do it...
Issues:
Fremantle UI not feature complete yet, and maybe some small bugs. I recommend it highly though...
And as always - disable extras-devel when you are finished...
