I wasted numerous hours compiling cairo/pango on Mac OS X. I don't like
fink or macports, since there is always a package I want or depend on,
which doesn't compile. I actually succeeded just to find out, that there
is a much easier way to get these libraries.

1) Download GTK_2.18.5-X11.pkg package from http://r.research.att.com/
and install it

2) Add to your .profile file in the home directory
export PATH=/Library/Frameworks/GTK+.framework/Resources/bin:$PATH

and you are done. This GTK framework is not official, since the gtk-osx
project doesn't provide one (you need to build one yourself). The above
is from the R for OS X development page, but seems to work fine.

ctest --verbose seems to work fine for the cairo drivers, so eventually
this is a very easy way (and fast) to get the cairo drivers running on
mac os x.

I updated the wiki accordingly:

That's true, no compiling needed, just install the SDK. The instructions
are in the wiki:
