Can't install 0.2.5 with pip. See below for install log with errors in it.

"python setup.py install" works.

Using Python 2.7.3, pip 1.2, in a virtualenv.

The best fix would be to include the generated core.c file on the gevent-zeromq PyPI packages, so that Cython is not required when installing the module.

There are two workarounds I know of:

1. Install manually, running python setup.py build && python setup.py install on the gevent-zeromq tree.
2. Install Pyrex (from the same requirements file, for example) before installing gevent-zeromq, this somehow "fixes" setuptools into thinking it should compile the extension.
