[cairo] Trouble building cairo-0.1.22 on Mac OS X

[Stephen Bespalko]

Greetings. I would like to consider helping out on the OS X side, but 
at this point I can't build cairo to determine whether participation 
would be appropriate. The pothole I'm stuck in is with regard to 
building libpixman. Autogen fails with the output below.

There are also problems, at least on OSX, with compiling parts of the 
XML support needed to build the documentation. If this is the 
appropriate list to report such problems, please let me know.

A brief explanation of what an OS X backend would consist of would be 
help me evaluate whether I can undertake such an endeavor.

Best regards,
Stephen Bespalko
