Steve,
Understood. I expected to have to pull in a significant portion
of OpenSSL(libcrypt actually). What I don't understand right now is
why I can't configure out the non-memory BIOs. If the BIOs provide an
abstraction layer for the IO, shouldn't the non-memory BIOs be easily
separable? I am working off limited understanding of the BIOs, so
clarification/correction will be well received.
Thanks again.

Steve,
Since I'm building a static object, I'll only pull the referenced
symbols. As I'm only going to be using memory BIOs, the rest of the
non-memory BIOs should get excluded during the link. I'll have to
short circuit the build to skip building the non-memory BIOs. Does
that sound plausible? Or am I way off the mark?
