Have you ever found yourself in this position? Your sysadmin is awesome. Your sysadmin is also busy and does not install software in a timely fashion. You could install what you need in easily if only you had root privileges.
The truth is that most software does not require root privileges to run. Root privileges are only needed to install the software in sensitive directories. There is generally no reason why a local user install will not work.
This post will cover installing software in $HOME/local. Specifically, the keychain utility will be built from source and manually installed. Root privileges are specifically not required.
First, create $HOME/local.
Add $HOME/local/bin to your path in $HOME/.profile. If you are not using sh, this line may belong in another file. Adding $HOME/local/bin before $PATH is important. You probably want your local install to take precedence over a system wide installation.
Reload $HOME/.profile so changes take effect.
Clone the keychain git repository into $HOME/local.
Build and install keychain. So far as I can tell, keychain needs to be manually installed on systems that do not support RPM. Other software may have options to configure the installation directory. In any case, a manual installation is a valuable experience.
The keychain utility and man page should now be available.
Finally, consider letting your sysadmin know what you installed. A system wide install may make sense.
