[libav-tools] avconv - mixing two audio files

I just started using avconv in order to mix two audio files. So in the online documentation I found the following command:
avconv -i INPUT1 -i INPUT2 -filter_complex amix=inputs=2:duration=first:dropout_transition=3 OUTPUT
However, running this gives me the following error:
Unrecognized option 'filter_complex'
Failed to set value 'amix=inputs=2:duration=first:dropout_transition=3' for option 'filter_complex'
If I understand this correctly, also by reading the manual on ubuntu, the filter-complex part is not defined (not configured?).
I have been trying to find a solution for some time now, but can't find anything.
I currently have version 0.8.3-4:0.8.3-0ubuntu0.12.04.1 of avconv.
Unfortunately, I'm not very experienced with this so maybe someone can tell me if I have to change something in the configurations
or use a different version of avconv. In case you know any other methods with which I could mix the audio files, please let me know.
Thank you for your help.
