rheve: I know. I can't figure the folding thing out. I have a few suspicions, and I will try them one-by-one, after I implement all the items on the TODO list. The hardware key is a good idea though. I was tapping-and-holding on it, and then cancelling the popup menu

pumo: Have you added the Maemo Hackers repository ? If so, you can install a package called "becomeroot". Follow the instructions here:
http://maemo.org/maemowiki/HowTo_EASILY_BecomeRoot
When installing osso-xterm, however, make sure you get the Maemo Hackers version, not the actual Bora version. You can tell them apart, because the Maemo Hackers version has the letters "mh" in the version number.

Then, find the terminal in "Extras", run it, and type
sudo gainroot
apt-get install gaim

This is basically what application manager does behind the scenes. Unlike with application manager, however, you should receive a message that tells you what's actually failing. You could post that message here, or it may even be helpful enough for you to figure out how to get gaim installed.
