In order to use the wmsplugin you have to compile webkit-image. See http://wiki.openstreetmap.org/wiki/JOSM/Plugins/WMSPlugin#webkit-image_.28QT.29 for reference. The file can easily be compiled with qmake: moc webkit-image.cpp > webkit-image.h qmake -project -o webkit-image.pro "CONFIG+=qt" "QT+=webkit" "TARGET=webkit-image" webkit-image.cpp qmake make
One could also "emerge gnome-web-photo" and set this as the default downloader in the josm wsm preferences. http://wiki.openstreetmap.org/wiki/JOSM/Plugins/WMSPlugin#gnome-web-photo_for_Fedora_and_Ubuntu
