The compilation of cairo 1.0.2 fails with already defined symbol "_cairo_pixman_composite". After browsing the source-code I included some #ifdef _PIXMAN_H_ ... #endif in pixman/src/pixman-remap.h. After that, compilation was successful again, but I don't know, if my changes result in desired behaviour. I used gcc 3.4.3 and gcc-4.1 respectively.
Given the removal of pixman from the source tree and that cairo (and pixman) master compiles cleanly on amd64/sid, I'd say this bug is obsolete. Please reopen if you have evidence to the contrary.
