Here is what worked for me.
1) Take note of the missing dependancies.
2) Try step 7, if that doesn't work then try the following steps
3) Find the repository the library resides in and make sure it's active (use search tool at gronmayer).
4) Install the repository from gronmayer or make sure it's enabled in Application Manager.
5) If you are still getting errors make sure there aren't conflicts. For example gronmayer lists extras/devel twice, once for Chinook once for Diablo. For GCompri, I had to install gstreamer0.10-plugins-ivorbis from Chinook, then disable the chinook repository because the rest of the dependancies were in Diablo.
6) Close Application Manager, it prevents the command line from installing.
7) Enter X terminal commands:
sudo gainroot (Needs rootsh installed)
apt-get autoremove (cleans up unusable and unused packages)
apt-get install gstreamer0.10-plugins-ivorbis (should work for any other missing package?)
You should get a few prompts confirming the install or an error message why it didn't.
8) Return to Application Manager and Install your program.
