Note that there are RPMs available from Internet2 for RHEL 4 and 5. For other platforms, or if you prefer not to use these RPMs, the Touchstone team maintains a source tarball of tbe Shibboleth SP, including all of its immediate prerequisites (curl, log4shib, xerces-c, xml-security-c, and opensaml), and a script to perform the entire build, in the touchstone locker, in /mit/touchstone/shibboleth/source/shibboleth-sp-sources.tgz.
The script can build the software on Linux and Solaris systems; note that you will to need to have Apache httpd (preferably 2.x, though 1.3 should also work) and OpenSSL (0.9.7 or higher) installed on the system, including their development packages. On Solaris systems, you must have the native Sun C/C++ compiler installed; Athena Solaris machines have this available, via attachandrun scripts and the sunsoft locker, but this requires that you have AFS tokens for the athena cell. Solaris machines must also have GNU make (gmake) installed.
To build from this, create a build directory, and unpack the source tarball into it; use the build-sp.sh script as follows:
# sh build/build-sp.sh [-a <apxs_path>] [-p <install_prefix>] [-s openssl_prefix]
The -a option argument is the path to the Apache apxs executable, e.g. /usr/local/apache2/bin/apxs (defaults to using the apxs in the PATH). The -p option specifies the install prefix (defaults to /usr/local/shibboleth). The -s option specifies the install location of the version of OpenSSL you want to build against, e.g. /usr/local/ssl (defaults to finding OpenSSL in standard system library locations).
Once you have built the software successfully, you will need to configure and customize it for use.
