+You will need working installations of Zlib and libcrypto (LibreSSL /

Zlib 1.1.4 or 1.2.1.2 or greater (ealier 1.2.x versions have problems):

+libcrypto (LibreSSL or OpenSSL >= 0.9.8f)
+LibreSSL http://www.libressl.org/ ; or
+OpenSSL http://www.openssl.org/
-(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1
-Blowfish) do not work correctly.)
+LibreSSL/OpenSSL should be compiled as a position-independent library
+(i.e. with -fPIC) otherwise OpenSSH will not be able to link with it.
+If you must use a non-position-independent libcrypto, then you may need
+to configure OpenSSH --without-pie.
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
