Installing Perl modules under Mac OS X - update

Here are instructions for current versions of Mac OS X (10.5 - Leopard) and XAMPP (0.7.4)

XAMPP is now available in the form of a disk image file (.dmg) rather than StuffIt Expander (.sitx). Safari will automatically mount this disk image and start the installer. If you're using a different browser, you'll need to double-click on the downloaded file to mount it and start the installation process manually.
You'll need the "make" command available as part of the Xcode tools; these are available from http://developer.apple.com/mac. The current download file is named xcode312_2621_developerdvd.dmg; beware - this is nearly 1GB in size. Mount the image, accept the defaults (System Tools, Unix Development Support), and proceed to install.
You'll also need various configuration and header file for the build process; get these by downloading the XAMPP "Developer package". The current version is xampp-macosx-0.7.4-dev.tar.gz; open this archive and copy the contents of the xamppfiles directory to /Applications/xampp/xamppfiles. One way to do this is:
cd /Applications/xampp
sudo tar zxvf ~my_user_name/xampp-macosx-0.7.4-dev.tar.gz
The DBI and CGI modules can be installed using the same commands listed in the book. To install DBD::mysql, follow these steps:
sudo /Applications/xampp/xamppfiles/bin/cpan
cpan> o conf makepl_arg --mysql_config=/Applications/xampp/xamppfiles/bin/mysql_config

cpan> install DBD::mysql

cpan> quit
