-(OpenSSL 0.9.5a is partially supported, but some ciphers (SSH protocol 1
-Blowfish included) 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.
supports it. PAM is standard on Redhat and Debian Linux, Solaris and
HP-UX 11.
-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. If you don't you will have to rely on ssh-rand-helper, which
-is inferior to a good kernel-based solution.

+GNU Make:

+OpenSSH has only been tested with GNU make. It may work with other
+'make' programs, but you are on your own.

+PCRE (PERL-compatible Regular Expression library):

+
+Most platforms do not require this. However older Unices may not have a
+posix regex library. PCRE provides a POSIX interface.

S/Key Libraries:

need a working installation of GNOME, including the development
headers, for this to work.
+--with-random=/some/file allows you to specify an alternate source of
+random numbers (the default is /dev/urandom). Unless you are absolutely
+sure of what you are doing, it is best to leave this alone.
+
--with-prngd-socket=/some/file allows you to enable EGD or PRNGD
support and to specify a PRNGd socket. Use this if your Unix lacks
/dev/random and you don't want to use OpenSSH's builtin entropy
--with-4in6 Check for IPv4 in IPv6 mapped addresses and convert them to
real (AF_INET) IPv4 addresses. Works around some quirks on Linux.
---with-opensc=DIR
---with-sectok=DIR allows for OpenSC or sectok smartcard libraries to
-be used with OpenSSH. See 'README.smartcard' for more details.

If you need to pass special options to the compiler or linker, you
can specify these as environment variables before running ./configure.
For example:
