I hit a similar problem to this today, although perhaps not exactly the same issue:

When I tried to build the latest release of WebKitGTK+ (2.9.5) right from the tarball in a 32-bit Linux system withOUT cairo-gl available, ACCELERATED_2D_CANVAS was enabled by default, making the build fail later on with a similar error to the one above, due to "missing cairo-gl.h".

I have no idea why it enabled 2D_ACCELERATED_CANVAS by default, I've just noticed it when I saw the build failing, because of this line in CMakeCache.txt:

  //Toggle accelerated 2D canvas support
  ENABLE_ACCELERATED_2D_CANVAS:BOOL=ON

Will try to provide more info later on, but for now just to mention that I was not using the build-webkit script at all, as I was building straight from the tarball.
