#   pip 1.4 doesn't fix it (1.3 did)
# - httplib2 0.8 permissions are 600 in the package and
#   pip 1.4 doesn't fix it (1.3 did)
# - RHEL6:
#   - set selinux not enforcing
#   - (re)start messagebus daemon
#   - remove distro packages python-crypto and python-lxml
#   - pre-install hgtools to work around a bug in RHEL6 distribute
#   - install nose 1.1 from EPEL
