You will need working installations of Zlib and OpenSSL.
-Zlib 1.1.4 or 1.2.1.2 or greater (ealier 1.2.x versions have problems):

-(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1
-Blowfish) do not work correctly.)
+RPMs of OpenSSL are available at http://violet.ibs.com.au/openssh/files/support.
+For Red Hat Linux 6.2, they have been released as errata. RHL7 includes
+these.
-The remaining items are optional.
-
-NB. If you operating system supports /dev/random, you should configure
-OpenSSL to use it. OpenSSH relies on OpenSSL's direct support of
-/dev/random, or failing that, either prngd or egd. If you don't have
-any of these you will have to rely on ssh-rand-helper, which is inferior
-to a good kernel-based solution or prngd.
-
-PRNGD:
-
-If your system lacks kernel-based random collection, the use of Lutz
-Jaenicke's PRNGd is recommended.

specific paths, for example:
./configure --prefix=/opt --sysconfdir=/etc/ssh
This will install the binaries in /opt/{bin,lib,sbin}, but will place the
configuration files in /etc/ssh.

-then you will also need to create the user, group and directory used by
-sshd for privilege separation. See README.privsep for details.

If you are using PAM, you may need to manually install a PAM control
file as "/etc/pam.d/sshd" (or wherever your system prefers to keep
them). Note that the service name used to start PAM is __progname,
There are a few other options to the configure script:
