Note that this patch has not yet been integrated into upstream

We have also fixed several compiler warnings found in the code. The
version of pyOpenSSL you find in the source release has those patches

Binaries are available for Linux x86 and x64 as well as Windows x86
and Mac OS X PPC/Intel. They include pyOpenSSL and the necessary

versions and allow easy integration of the archives into buildout
