Adding other services to Action Streams?

Is it possible to add other serivces? I wish to add a stream for deviantART. I tried to configure stream.yaml for deviantART, but in the logs I get:

Impossible de charger la classe ActionStreams::Event::deviantART pour le flux deviantart art : Can't locate ActionStreams/Event/deviantART.pm in @INC (@INC contains: /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/CommunityActionStreams/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/WXRImporter/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/Motion/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/spamlookup/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/mixiComment/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/feeds-app-lite/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/TypePadAntiSpam/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/StyleCatcher/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/FacebookCommenters/extlib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/FacebookCommenters/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/ActionStreams/extlib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/ActionStreams/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/Textile/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/WidgetManager/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/plug ins/MultiBlog/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/addo ns/Commercial.pack/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/addo ns/Community.pack/lib /home/nlaplante/nlaplante.com/cgi-bin/mt/extl ib /home/nlaplante/nlaplante.com/cgi-bin/mt/extl ib lib /etc/perl /usr/local/lib/perl/5.8.8 /usr/local/share/perl/5.8.8 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.8 /usr/share/perl/5.8 /usr/local/lib/site_perl .) at (eval 652) line 1.
