To install, just run the usual dance, ./configure && make install. Run
./autogen.sh first to generate the configure script.

To compile under Windows, install MinGW and MSYS then select the common packages (gcc, automake, libtool, etc).
To compile under OS X with homebrew, you will need
to install the following dependencies first: brew install autoconf automake libtool.
