Hello openssl-team!
Can you help me understand what is going on? Or just do not
let openssl-engine install itself over the normal ssl-libs?
I know you warned saying that openssl-engine package is not
stable. However source is exactly the same. How come then that
the compilation of the ssh configure script test for openssl
fails if I link against the libs made in openssl-engine ??
Dont worry about the ssh, it is up and running now. I just wonder
what is going on in the engine-library? It will try to install
itself as a replacement for the "normal" libcrypto.a, you know.
