What bug, the custom OpenGL viewport IPR?
The current OpenGL IPR is available only for Windows and Linux currently due to some limitations under OSX in the lib that I'm using to manage the window. The MPlay IPR should work fine, but it is true that it doesn't support the picking functions. I'm thinking about how to work around these limitations, or even how to integrate the IPR in the Houdini render view panel.
