No, binary/source of your plugin.  I have the Qt stuff.

Or maybe I misunderstood your plugin - did you try a C++ version?  Or  
is it only python?  Maybe that is the problem, the Qt SQL plugins,  
when bundled in Qgis, would be seen by the Qgis binary and any C++  
plugins, but maybe the bundled PyQt can't see those.  Maybe it works  
when the Qt SDK is installed because PyQt looks in the default Qt  
plugin folder (even though Qgis looks in the Qgis app bundle).

Tom - do you know if PyQt uses the same qt.conf in the Qgis bundle  
that Qgis itself uses?  Or is there a way in Python to set the plugin
