Mac OS X Leopard comes with Apache2 and PHP pre-installed, but no MySQL. This is the missing link in the very useful MAMP setup. The kind people at mysql.com offer it ready packaged for mac users. When picking your version, MacIntel users pick the 32-bit version, unless you want problems installing Perl's DBD::mysql. What is DBD::mysql? the very useful module that allows Perl scripts to access your MySQL databases. If you install the 64-bit version of MySQL you will hit errors when you install DBD::mysql as a 32-bit installation of Perl is not interested in compiling against 64-bit MySQL libraries.If you need 64-bit MySQL you could install both versions and compile against the 32-bit libraries.
