The SSL libs are needed for both hashlib and the ssl module
(which is used to e.g. implement HTTPS downloads).
My guess is that either the libssl has a different version on
your system or perhaps just a different name. We're building
pyrun against OpenSSL 1.0.1 at the moment, which uses the
above so-name for the lib.

Additional libraries can be included in pyrun, but only if the
libs can be statically linked and the Python extensions interfacing
to them support static linking as well.
One of the things we'd like to do is make the configuration of
such things easier. At the moment, this requires digging deep
into the way the pyrun is built.
You have to add a corresponding section for the Python extension
to Runtime/Setup.PyRun-2.7 and the include_list in Runtime/makepyrun.py

This depends on how much work is involved. We generally try to help
people as much as we can without requiring a support ticket, but
there are limits to this, of course.
