you need the latest gdk-pixbuf to build evolution now.

2000-04-11  Larry Ewing  <lewing@helixcode.com>

	* widgets/e-table/e-cell-toggle.c (etog_draw): update for new
	gdk-pixbuf.  Added a disabled chuck of code to do alpha blending
	on pixmaps.

	* widgets/shortcut-bar/e-icon-bar.c (flatten_alpha): update for
	new gdk-pixbuf.
