This enables CI builds on http://travis-ci.org/. Please see also:
http://travis-ci.org/#!/saltstak/salt.
Travis uses 32-bit Ubuntu Linux 11.10 (server edition) plus some
additional repositories, like RabbitMQ's own repo which provides the
zeromq package. This already contains the zeromq development headers
and libraries necessary to build Python extenstions in C. FYI - This
zeromq packake doesn't play nicely with the standard Debian/Ubuntu
zeromq packages like libzmq-dev. Also included are libssl-dev and
python-dev (but swig is missing). See also:
http://about.travis-ci.org/docs/user/ci-environment/
One complication is that M2Crypto requires SSL Version 2 support in
libssl. Debian and Ubuntu have disabled Version 2 support in libssl
since Version 2 is know to be insecure. We use our own source tarball
of M2Crypto that has been patched with the Debian/Ubuntu patches that
remove SSL Version 2. Please see:
http://packages.ubuntu.com/oneiric/python-m2crypto.
Salt also requires unittest2 which must be installed when using Python
2.6. unittest2 comes included with Python 2.7.
