sci-libs/scikits_learn depends on dev-python/joblib, no version constraints. While it runs fine with <=dev-python/joblib-0.9.4, it does not run with joblib-0.10.0 (find runtime error message below). Proposed quickfix for affected systems: mask joblib-0.10.0 Proposed fix: add a version constraint to scikits_learn's ebuild.

A fix is in https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=d71430e877ec01acffeb3f9d988c09103c0fb78a with a version bump. `from sklearn import tree` works for me on python-2.7. Please test if it works for you.
