qwt designer plugin on MacOSX

hello
thanks to this forum I succesfully installed QWT included the designer plugin on my Mac. Yet I have new troubles concerning the QT designer. Although the libqwt_designer_plugin.dylib plugin seems in the right directory (/Developer/Applications/Qt/plugins/designer) i do not have access to the qwt elements when opening the designer.
Anyone got an idea ?

Excuse me, did you manage to solve this problem? I googled interned and found only your question concerning this subject. Can you share your decision if you have?

Hi,
Have you found a way around this?
