New version from upstream (12.11) with 136 activities. I tried to fix gnuchess dependency, but made mistake.

-maemo2 is already built but waiting to the repository. It contains also fix for explore.py:545. And fix for three other games: braille_alphabets braille_lotto color_mix.

There are still some games which are not working, and some which are not tested on N900.

List of known issues:
*Falling words: can't write words with double letters (e.g. "less")

*Watering can and sweeping game: Currently game can't be played (expects mouse movement without dragging)

*Miner: can't be played, needs mouse wheel

Report more. I will then check what I can fix or if upstream is interested to fix or should they be dropped entirely from maemo-version.
