problems with the ribbon

I'm trying to plug the component tms, and was going all right until I have problems with theribbon and other components.
I changed the demo1, putting a ribbon on it, and SamplePluginOne_XE2 plugin (bpl) declare the uses in vcl.ribbon. When I compile the SamplePluginOne_XE2, required in thepackage is added vclribbon.dcp, so far there all normal, however, when I load the plugin displays the following error message: "A class named TRibbonApplicationMenuBaralready exists." This also happens using the DevExpress components.
What can I do?
thank you

Is vclribbon.dcp also in requires list of main EXE?

resolved. tks
