Compiling Mac client?

I'm interested in getting the ES mac client to display the album cover from iTunes while ES is displaying
the screen saver animations and set to play music in iTunes. I've downloaded the source and found the "ElectricSheep.xcodeproj"
file in the "client_osx" folder. Double clicking this file brought you into XCode but clicking on "Build" or "Build and Go"
within XCode gives me some errors about jcapimin.c and jcapistd.c and missing input files. Apparently, I should
have a directory called "jpeg-6b" on the same level as "client_osx" : "electric sheep/trunk/client_osx/../jpeg-6b/jcapimin.c".
I guess I should hunt around for jpeg-6b and maybe some other things. Is there any documentation around for
building the Electric Sheep mac client using XCode? I'm an XCode/Objective-C/MacOSX newbie. Thanks!

never mind

I found the jpeg-6b code and placed it where it needed to be and things got built
in Xcode. Now I have to get to hacking and trying to add the album cover overlay.
