After unpacking the release tarball:

$ tar -zxf mpi4py-X.X.X.tar.gz
$ cd mpi4py-X.X.X

[openmpi]
include_dirs = /usr/local/mpi/include
libraries = mpi
library_dirs = /usr/local/mpi/lib
runtime_library_dirs = /usr/local/mpi/lib

and then run the build command, perhaps specifying you custom configuration section:

$ python setup.py build --mpi=openmpi
