Fixing openssl errors on OS X with anaconda python distribution

anaconda openssl

OS X ships with an ancient version of openssl and I ran into problems using starcluster with Anaconda python distribution (APD).

Every starcluster command failed with the following error:
SSLError: [Errno 1] _ssl.c:504: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

The continuum guys are working on fix. Meanwhile a quick workaround is to use homebrew to build python with a newer openssl version and then substitute the _ssl.so in APD with the homebrew _ssl.so


1) brew install python --with-brewed-openssl

2) Go to anaconda/lib/python2.7/lib-dynload and 

ln -s /usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/_ssl.so _ssl.so

In [1]: import ssl

In [2]: ssl.OPENSSL_VERSION
Out[2]: 'OpenSSL 1.0.1e 11 Feb 2013'

And now everythings works as expected with starcluster.
