Perl is used on the kernel Makefile to generate documentation, firmwares in c source form, sources, graphs, and some headers. Documentation/Changes does not list Perl 5 and the following modules: Getopt::Long, Getopt::Std, File::Basename, and File::Find. I noticed this when building the kernel on a openmoko GTA02 using distcc for some bechmarchs
