ubuntu studio 12.10にてopenframeworksをインストールしようとしているのですが次のエラーメッセージの意味がよくわからくて困っています。

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libavformat-dev : Depends: libavformat53 (= 6:0.8.6-0ubuntu0.12.10.1) but it is not going to be installed
libavutil-dev : Depends: libavutil51 (= 6:0.8.6-0ubuntu0.12.10.1) but it is not going to be installed
libswscale-dev : Depends: libswscale2 (= 6:0.8.6-0ubuntu0.12.10.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
error installing packages, there could be an error with your internet connection

これはubuntu12.10.1で実行しろと言うメッセージなのでしょうか?　どなたかアドバイスをお願いします。
