I'm not so sure that making the label insensitive will do anything,
since the label is generally a GTK_NO_WINDOW widget that doesnt
recieve events... and the notebook itself probably uses the same
GdkWindow for all tabs (so it wouldnt make sense to set them all
insensitive)...

you could:
   o Disable the tabs and implement the tab navigation in another way
      (radio buttons ?)
   o Set the entire page insensitive when its prerequisites are not met.
