For building under Debian? Mike’s message on the webkit-dev list.

First do not down load any of the graphics related libraries using Fink.

Follow the instructions here http://developer.imendio.com/projects/gtk-macosx/build-instructions

Next you have to upgrade the cairo version. I used git to grab the latest from opendesktop.

http://cairographics.org/download/

And you may need a full copy of IBM’s ICU

Here is my jhbuild stetup script.

svn co http://svn.gnome.org/svn/jhbuild/trunk jhbuild

Install into ~/bin:

(cd jhbuild && make -f Makefile.plain install)

Cairo git clone git://anongit.freedesktop.org/git/cairo git clone git://anongit.freedesktop.org/git/pixman

Finally you need this patch the cairo OSX port is broken so we fallback to a image buffer. A braver soul than me could push the changes to apple. Hendry ??
