You have done good. Pretty much the cause of action i would have taken.

To bad it didn't solve your problem. Moodlight have a dependecy problem. It need pygame that is newer or equal to v1.8.1 installed. It will therefore not install the this version cause that might cause a dependency problem for another program depending on another version. If i remember the older/newer correct (< =older; > = newer).. it could be the other way around.

As you can see here.
moodlight: Depends: python-pygame (>= 1.8.1release-0maemo1) but it is not going to be installed.

I was hoping autoremove would solve this for you.. cause it will install or uninstall programs in the pipe. Now you could try uninstalling the 2.0.9 and hope it not breaks anything. I think it will be no problems cause you said you installed it manually before.

First i like you to try an upgrade.. that might install the newer versions of python.

1. sudo gainroot
2. apt-get upgrade

Then remove the package that casue problem:
1. sudo gainroot
2. apt-get remove libsdl-ttf2.0

you might also want to try:
1. sudo gainroot
2. apt-get remove python-pygame

And then try install moodlight again:
1. sudo gainroot
2. apt-get install moodlight

You could try applie the "-f" force option.. it could be dangerous as it will force the installation. (apt-get -f install moodlight)

I guess you understand "sudo gainroot" and that you only need to do it once to get to the root shell.
