Build Cython and gevent on OSX

When I build gevent, I get an error

    Traceback (most recent call last):
  File "/usr/local/Cellar/python/2.7.1/bin/cython", line 7, in

    import Code
ImportError: dlopen(/usr/local/Cellar/python/2.7.1/lib/python2.7/site-packages/Cython-0.14.1-py2.7-macosx-10.4-i386.egg/Cython/Compiler/Code.so, 2): no suitable image found.  Did find:

I tried开发者_如何学C to specify architecture with CFLAGS="-arch x86_64", but it does not work.

Recompilation gevent-1.0dev and greenlet with flags CFLAGS="-arch i386 -arch x86_64" is a solution to my problem.

The gevent releases include the generated .c sources so you don't need Cython to build them.

The development version (1.0) also has automatically generated tarballs that includes those .c files: http://code.google.com/p/gevent/downloads/list
