vst support not working in qtractor 0.11?

Hey, very nice app, it's also really cool that it has support for so many plugin types.
Ladspa and dssi plugins show up ok in the plugins menu.
However, vst plugins don't show.
I configured all plugin folders in the "View->Options->Display" Dialog.
I also set the environment variable VST_PATH to point to the same directory.

One thing I noticed when building qtractor was some warning (not error) messages when compiling qtractorVstPlugin.cpp. Here's part of the compile output,maybe that'll help:
g++ -c -pipe -msse -mfpmath=sse -ffast-math -O2 -Wall -W -D_REENTRANT -DQT_SHARED -DQT_NO_DEBUG -DQT_XML_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtGui -I/usr/include/qt4/QtXml -I/usr/include/qt4/QtXml -I/usr/include/qt4 -Isrc -I/tmp/xfs/qtractor-0.1.1/vstsdk2.4/pluginterfaces/vst2.x -I/usr/include/qt4 -I/usr/local/include -I/usr/include -I/usr/include/qt4 -I. -I. -o qtractorVstPlugin.o src/qtractorVstPlugin.cpp

src/qtractorVstPlugin.cpp: At global scope:

Is that warning message normal?
Thanks
