"""
Hack to build our Python extension module.
In a sane world, we'd just use the excellent distutils package, which
would do all the work for us. But we have this little problem of
sometimes needing to use a private copy of the OpenSSL libraries to
kludge around obsolete system libraries, and a further problem that
GNU ld has bizzare issues with linking static libraries into shared
objects on 64-bit platforms.
In the long term, this problem will go away, when everybody updates to
a reasonable version of OpenSSL with CMS and RFC 3779 support enabled.
When that happens, this whackiness should be replaced by a normal
setup.py using distutils.
In the meantime, we pull config information from distutils, but do the
build ourselves.
This is a minimal hack to get the job done, and probably a bit
fragile. Much of the code is taken from python-config and the
distutils.sysconfig.customize_compiler. If there's any real
documentation on how to do this sort of thing, I have not found it
yet. YMMV. Beware Of Dog.
