Blosc is a Python module designed to be a binary data high-performance compressor class.
Assuming that you have a C compiler installed, do:
python setup.py build_ext --inplace
It supports Python 2.6, 2.7 and 3.1 or higher versions.
After compiling, you can quickly check that the package is sane by running:
PYTHONPATH=. (or "set PYTHONPATH=." on Win)
export PYTHONPATH=. (not needed on Win)
python blosc/toplevel.py (add -v for verbose mode)
python setup.py install
