### Error when try to republish theora

Hi there,

I am trying to republish theora to raw with image_transport package, but I got the following error when I did that.

adrian@ubuntu:~/catkin_ws/src/camera1394/tests$rosrun image_transport republish theora in:=camera/image_raw raw out:=camera/image_decompressed terminate called after throwing an instance of 'image_transport::TransportLoadException' what(): Unable to load plugin for transport 'theora', error string: Failed to load library /opt/ros/groovy/lib//libtheora_image_transport.so. Make sure that you are calling the PLUGINLIB_EXPORT_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Could not load library (Poco exception = /opt/ros/groovy/lib//libtheora_image_transport.so: undefined symbol: th_comment_clear) Aborted (core dumped)  Following is output of topic list: adrian@ubuntu:~/catkin_ws/src/camera1394/tests$ rostopic list
