[gnome-love] Error Building Gnome 3 using jhbuild on Arch Linux x86_64

[Zach Dziura <zcdziura gmail com>]

I'm running into an error when I try to run jhbuild build on my Arch Linux box. I'm trying to pull down the gnome-shell code, when I get a compilation error. Here's the error message I receive:

*** Building WebKit *** [33/75]

make: *** [DerivedSources/WebCore/ColorData.cpp] Error 2

*** Error during phase build of WebKit: ########## Error running make   *** [33/75]

Obviously, something is wrong with WebKit. I don't know if it's that particular C++ program that's being funky, or if I don't have a particular package installed on my system. Any help from anyone who's experienced this before?
