OK, I admit - it's bad habit to anwer to yourself ;) but I found how to make way around this problem:
edit: oe/packages/task/task-openmoko.bb and comment out openmoko-rssreader in it. Now you can compile OM (without rssreader) and compilation does not brake. I also found that others hve the same problem: http://zecke.blogspot.com/2007/07/webkitgtk.html So maybe it helps someone. Although I responded myself, the question in my first post remains - how to fix building process of OM because apparently it is broken. regards cayco
