This installation shell script will examine your system and ask you questions
to determine how the perl5 package should be installed. If you get
stuck on a question, you may use a ! shell escape to start a subshell or
Unix system. If despite that it blows up on yours, your best bet is to edit
Configure and run it again. If you can't run Configure for some reason,
you'll have to generate a config.sh file by hand. Whatever problems you
