I would install the openssh server package if you have a choice
apt-get install openssh-server. However if you want to compile from source install openssl first.
Either from source or from the package:
apt-get install libssl-dev openssl
To install dependencies needed to build a given package, you can use apt-get's build-dep option, e.g.,
apt-get build-dep openssh or
apt-get build-dep openssh-server if you are trying to build the server.
It's likely you are missing the development headers for openssl. Try installing "openssl-devel".
