Installing SSH2

Please Note: The installation of SSH2 requires Installing_PHP5 or Installing_PHP4.
If you are unable to do so, then you may not be able to use SSH2 on your DreamHost account.

Below is the install script for the SSH2 PHP module. I'm not a bourne/bash scripter so I am aware the code below is shit.

installssh2forphp.sh

#!/bin/sh
set -e

#### User Configuration Options
# Temporary src directory - WARNING: This will be wiped clean.
SRCDIR=${HOME}/src

# Note: This *MUST* be set to your PHP5 installation directory!
PHPDIR=${HOME}/php5

PREFIXDIR=${HOME}/prefixdir

## Program Version Configuration
