# Dapper ships with older versions of Twisted (2.2.0) and Nevow (0.6.0), and
# (unlike newer distributions) they are not installed with .egg meta-data
# directories. As a result, they are invisible to setuptools. When the
# 'build-deps' target thus builds Nevow, it will fail unless Twisted-2.4.0 or
# newer is available, so Dapper users must install a newer Twisted before
# running 'make build-deps'. In addition, through some not-yet-understood
# quirk of setuptools, if that newer Twisted is in /usr/local/lib , somehow
# the build still manages to pick up the old version from /usr/lib . It turns
# out that importing twisted now, before use_setuptools() is called, causes
# setuptools to stick with the correct (newer) Twisted. This causes an error
# if Twisted is not installed before you run 'make build-deps', but having
# Twisted at this point is a requirement anyways.
