building hugin: error: expected class-name before '{' token

I've got the below error when trying to build hugin. As it turned out my wxWidgets were compiled without Drag&Drop support, even when I supplier --enable-dnd to the configure script.
It's because --with-x11 does not support it.

To find out if dnd is really enabled use

$ grep wxUSE_DRAG_AND_DROP /pat/to/build/dir/lib/wx/include/*/wx/setup.h

#define wxUSE_DRAG_AND_DROP 1
