Well, actually your problem isn't related to libssh2 in any way. I
would recommend that you study and follow the Linux From Scratch
tutorials in order to learn about building packages based on
autotools.

Why both --without-libgcrypt and --with-libgrypt-prefix?

I already asked you to stop using this ancient version. Use the most
recent code so that you avoid wasting your time and ours on bugs that
have already been solved.

Do you want to link statically against OpenSSL?

The above shows that the library has been built successfully.

And this shows that there is a bug in your version of libssh2 with
building examples statically. If this problem still exists in the
latest code we would obviously welcome a patch to the build files
that will fix these things.

If you don't care about the examples then I suggest downloading
the current git code. I have just pushed a commit which adds a
configure option to disable building of the example applications.

git clone git://git.libssh2.org/libssh2.git && cd libssh2 &&
./buildconf && ./configure --disable-examples-build followed by
your other configure options.
