through Xcode (several Gigs), both available from
Apple Developer downloads.
Xcode is also available through the
Store application. Some versions of the OSX install DVD or SSD come with the
'developer tools', which contains Xcode. Only the 'unix tools' section
of Xcode is actually required, no specific version of Xcode is needed,
the latest is available directly through the App Store.
To interact with the command line and run Perl commands, a terminal
application is needed. OSX comes with Terminal.app by default, there are
available as well.
