Error during build today and yesterday

[Jeroen Verhoeckx <jeroenverh2002 yahoo com>]

I tried to build gnome-shell today and yesterday.
When I did this I got the following error:

---------
tray/na-tray-child.c: In function ‘na_tray_child_get_wm_class’:
tray/na-tray-child.c:529: error: ‘NaTrayChild’ has no member named ‘icon_window’
make[3]: *** [libtray_la-na-tray-child.lo] Error 1

  [1] Rerun phase build
  [2] Ignore error and continue to install
  [3] Give up on module
  [4] Start shell
  [5] Reload configuration
  [6] Go to phase "wipe directory and start over"
  [7] Go to phase "configure"
  [8] Go to phase "clean"
  [9] Go to phase "distclean"
choice: 
---------

The file '~/gnome-shell/source/gnome-shell/src/gnome-shell' is also missing?

What can I do?

Thanks!
