I also had problems with the build I downloaded on June 4th. I could not render parts of the face until I re-textured them. It seems to be a Blender Import problem with the UV's (I was sure to use the new scripts also). Other than that, It looks great!!!
No worries, it's not the builds that are broken, it are the models in svn, so there's nothing to fix to the nightlies, just lots of modeling that needs to be done.
