Prerequisites: OS X (10.4)

Tested with the following language versions:

The "fink" package management tool has been used to install OS X library dependencies. "darwin-ports" may also be used, but this is untested.

The xmlsec1 library should be installed manually; download the tarball from: http://www.aleksey.com/xmlsec/download/xmlsec1-1.2.9.tar.gz.

Before building the source, apply the patch in the xmlsig scripts/ directory. To build, run the xmlsec1-autogen.sh script (from the same directory) in the base xmlsec1 directory. Building on OS X also requires the automake and pkgconfig tools from fink as well as the Apple XCode package, install as follows:
sudo apt-get install autoconf2.5 automake1.9 libtool14 pkgconfig
