import of skimage.morphology.selem.disk fails

Hello, "from skimage.morphology.selem import disk" fails with the message "ImportError: cannot import name convex_hull_image". Subsequent attempts to import result in message "ImportError: cannot import name _template". System: Python 2.7.2 on OS X 1.8.2 , scikit-image latest version from git Installed via "python install setup.py" The install seemed to work fine - I can run most other scripts. Full error log here: http://pastebin.com/hD8ishuH Any ideas? Best, Parand
