failed to load openni_kinect libraries

edit

I'm using my turtlebot for the first time with electric. Every time I try to roslaunch anything that uses packages from the openni_kinect stack (follower.launch, openni.launch, etc), I get a bunch of errors about failing to load libraries from openni_kinect. Here's an example of one of the errors.

[ERROR] [1337214239.808330340]: Failed to load nodelet [/camera/depth/metric_rect] of type [depth_image_proc/convert_metric]: Failed to load library /opt/ros/electric/stacks/openni_kinect/depth_image_proc/lib/libdepth_image_proc.so. Make sure that you are calling the PLUGINLIB_REGISTER_CLASS macro in the library code, and that names are consistent between this macro and your XML. Error string: Cannot load library: /opt/ros/electric/stacks/perception_pcl/pcl/lib/libpcl_visualization.so.1.1: symbol __cxa_pure_virtual, version libmysqlclient_16 not defined in file libmysqlclient.so.16 with link time reference

There are a bunch of similar errors all with libraries from the same stack. I've tried reinstalling that stack but to no avail. Hopefully this is something really obvious that I'm missing.

Thanks!
