One of Perl's strengths is its portability, it can be used on any system and it's an interpreted language, which means that the code doesn't need to be compiled and can be used directly. On SliTaz, Perl and Microperl are not installed by default on the LiveCD: you can either rebuild your ISO or install through the package manager.
