AssertionError ao usar o uwsgi com pypy com o aplicativo de teste de amostra

Question

Estou tentando obter o aplicativo python de teste de hello de amostra para executar usando o uwsgi com pypy. Eu tentei construir o uwsgi com o plugin pypy (usando python uwsgiconfig.py --plugin plugins/pypy ) e pypy no meu diretório home.

link

No entanto, quando eu uso o comando

 ~/uwsgi-2.0.4/uwsgi --plugin ~/uwsgi-2.0.4/pypy --http-socket :9090 --pypy-home ~/pypy-2.2.1-linux64/ --pypy-wsgi uwsgi_pypy_test.wsgi --pypy-lib ~/uwsgi-2.0.4/plugins/pypy/libpypy-c-x86_64_20130524.so

sai com OperationalError e AssertionError :

Alguém conseguiu pypy para correr com sucesso com o uwsgi? Estou tentando a configuração mais básica aqui, o que estou fazendo de errado?
