[yt-users] Warning: pip install mpi4py may not work as expected

Hi all,

Due to a recent change in pip and the python package index system doing

$ pip install mpi4py

will install mpi4py 0.6.0, a version from 2008.  This is due to a recent
decision to only allow pip to download packages from pypi for security

I've raised this issue with the mpi4py developers so hopefully this will be
fixed soon.

For now, mpi4py can be installed via:

pip install mpi4py --allow-external mpi4py --allow-insecure mpi4py

Or by downloading the source package tarball from the mpi4py package
release page on bitbucket and building manually:


Hope that avoids some confused debugging in the future,
