This has been tested by me on CentOS 5. It allegedly works on CentOS 4 as well.

# yum install gcc
# yum install openssl-devel
# yum install pam-devel
# yum install rpm-build
Grab a download of the Portable OpenSSH source from here: >>http://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/

Prepare, build and install the RPM. Disable the building of GUI components in the spec file. We don’t need these on a server:

# tar zxvf openssh-5.2p1.tar.gz
# cp openssh-5.2p1/contrib/redhat/openssh.spec /usr/src/redhat/SPECS/
# cp openssh-5.2p1.tar.gz /usr/src/redhat/SOURCES/
# cd /usr/src/redhat/SPECS
# perl -i.bak -pe 's/^(%define no_(gnome|x11)_askpass)s+0$/$1 1/' openssh.spec
# rpmbuild -bb openssh.spec
# cd /usr/src/redhat/RPMS/`uname -i`
# ls -l
-rw-r--r-- 1 root root 275808 Feb 27 08:08 openssh-5.2p1-1.x86_64.rpm
-rw-r--r-- 1 root root 439875 Feb 27 08:08 openssh-clients-5.2p1-1.x86_64.rpm
-rw-r--r-- 1 root root 277714 Feb 27 08:08 openssh-server-5.2p1-1.x86_64.rpm
# rpm -Uvh openssh*rpm

# service sshd restart
The RPM should install cleanly on CentOS 4. On CentOS 5, after installation, service ssh restart throws a warning that initlog is obsolete. I work around this by keeping a copy of the old /etc/init.d/sshd and restoring it after RPM installation.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
