Type 'make' to build the packet decoder, 'hairtunes'.

You need the following installed:
  openssl
  libao (if you use homebrew, use brew install libao)
  avahi (avahi-daemon running and avahi-publish-service on path, no need on Mac OSX)
  Perl

Debian/Ubuntu users need:
  libssl-dev libcrypt-openssl-rsa-perl libao2 libao-dev libio-socket-inet6-perl libwww-perl avahi-utils

Perl modules (install from CPAN if needed e.g. `perl -MCPAN -e 'install X'`):
  HTTP::Message
  Crypt::OpenSSL::RSA
  IO::Socket::INET6

MacOSX:
  * install XCode
  * install homebrew (https://github.com/mxcl/homebrew)
  * export ARCHFLAGS="-arch x86_64"
  * brew install pkg-config libao
  * make
  * perl -MCPAN -e 'install Crypt::OpenSSL::RSA'
  * perl -MCPAN -e 'install IO::Socket::INET6'
  * perl shairport.pl

  OSX 10.5 only bundles perl 5.8, which won't work with shairport.
  After getting a update here (http://www.perl.org/get.html), it worked.

How to run as a daemon on Mac 10.6
------
* cp hairtunes shairport.pl /usr/local/bin
* vi /usr/local/bin/shairport.pl, change the path of hairtunes from ./hairtunes to /usr/local/bin/hairtunes
* cp org.mafipulation.shairport.plist ~/Library/LaunchAgents/
* launchctl load org.mafipulation.shairport.plist
* launchctl unload org.mafipulation.shairport.plist (to remove)
