Just a simple example (there are lots of other apps like this):
[colin at jimmy ~]$ ldd /usr/bin/compiz| grep xcb
	libX11-xcb.so.1 => /usr/lib64/libX11-xcb.so.1 (0x00002b6192005000)
	libxcb-xlib.so.0 => /usr/lib64/libxcb-xlib.so.0 (0x00002b61940f2000)
	libxcb.so.1 => /usr/lib64/libxcb.so.1 (0x00002b61942f3000)


And these changes mean that:
1) libxcb-xlib is gone (due to:
http://gitweb.freedesktop.org/?p=users/cloos/libxcb.git;a=commit;h=e7b5d59c9aa187faf5142fda74eb11da04f8b1b7)
2) the major of libxcb has been bumped (due to:
http://gitweb.freedesktop.org/?p=users/cloos/libxcb.git;a=commit;h=e3637aea7a48beb0e5710d39448caf5904124d97)

That's why everything needs rebuilt.
