class Marble::MarbleWidget’ has no member named ‘addPlacemarkFile’

Hi, I go that:

(igotu2gpx-0.3.0)
compiling marblevisualizer.cpp
marblevisualizer.cpp: In member function ‘virtual void MarbleVisualizer::setTracks(const igotu::IgotuPoints&, int)’:
marblevisualizer.cpp:156:13: error: ‘class Marble::MarbleWidget’ has no member named ‘addPlacemarkFile’
make[1]: *** [.build/debug/marblevisualizer.o] Error 1

What could I do about it?

cheers
