cairo & gtk+ mutually dependent ?

[Rod Butcher <rbutcher hyenainternet com>]

I found that cairo requires some gtk+ libs and headers to build, yet 
gtk+ has cairo as a requirement. Am I missing the point somehow ?
I hadn't been able to find an up-to-date Gnome build sequence doc so I 
put my own together based on starting from scratch :-
libxml2
libxslt
gtk-doc
glib
libIDL
......
glitz
cairo
pango
atk
gtk+
.... etc

but cairo doesn't fit that anymore. ?
