Develop a Mac OS X installer framework Namoroka/Gecko, XAMPP

We need a solid Mac OS X installer framework to install Namoroka/Gecko, XAMPP (Apache, PHP and MySQL) on Mac OS X 10.4+. Purpose: Create an installer package for a Web Based standalone software solution. Should be ideally one DMG installer file. All installed components (Namoroka, XAMPP) should not conflict with existing versions of already installed Firefox or XAMPP. Web content (Ioncube PHP Encoder) is included in the package and will be installed with the installer pack. Option to check updates (and download) from the server should be available. Other requirements: - Pre-installer script to install XAMPP - Update (check for new versions) and upgrade installer (better version of software) module - Import for bookmarks etc after installation switched off - Ioncube PHP Encoder
