They did it this way intentionally.  The library is still there for existing \
applications that have already linked against it, but the headers have been removed \
to prevent developers from building new applications using it.  Given that the \
OpenSSL API has been a moving target that has broken binary compatibility, their \
solution, while a bit extreme, is not completely insane.

No, there's no GnuTLS by default.  I believe it can be built from source and OpenSSL \
definitely can for people who need it.

That did the trick, thanks:

$ grep SSL include/config.h
/* Define if you have the OpenSSL. */
/* #undef HAVE_OPENSSL */

On to the next build failure.
