To build the Shibboleth SP and its prerequisites (excluding Apache and
OpenSSL), you can copy and unpack the source tarball in:

    /mit/webauth/shibboleth/source/shibboleth-sp-sources.tgz

This contains the sources for curl, log4cpp, xerces-c, xml-security-c,
and opensaml, as well as shibboleth-sp.

That same directory has a build-sp.sh script, which you can run from
the top of the unpacked source tree.  It takes the following options:

  -a <apxs_path>
  -p <install_prefix>
  -s <openssl_prefix>

The default apxs executable is the one found in the PATH (if any).
The default install prefix is /usr/local/shibboleth.
The default openssl prefix is /usr/athena on Athena machines, / otherwise.
