Thanks for the careful report.

If there are places in the build instructions where a quick word about
prefix or PKG_CONFIG_PATH could be helpful, feel free to contribute a

These programs were never written as good demos --- just little tests
I needed --- so they do behave poorly. I just ripped out the
XSynchronize at least.
If people want to contribute some good demo programs, I would be glad
to throw away everything there that I wrote. Owen's cairo-knockout
should make it good base. It's double buffered at automatically scales
content as the window size changes.

Yes. And PostScript support will be coming soon. I'd like to put
together demos that demonstrate multi-device output from the same

I think the right place to start is with the pkg-config
developers. The source lives here:
and since I don't see a more focused mailing list, I'm guessing that
the general "xdg-list" would be appropriate:
(And, no, it's not obvious to me either that those two URLs would be
related at all).

Now that the internals have been reworked, it should be easy to make
Cairo ignore all of its X related implementation if X is not
available. All that is missing is someone to add the appropriate
autoconf magic. Any volunteers?
But I think you were actually asking for something different, which is
to let Cairo build against older versions of xft/xrender that can't be
found through pkg-config. This also requires some sort of autoconf
skill that I lack. I would be glad to commit patches though.
