$! That's it. If you get into a bind trying to build perl on VMS then
-$! definitely read through the README.VMS file as well as the top of the
-$! [.VMS]DESCRIP.MMS file.

You have the option of continuing the configuration process, despite the
distinct possibility that your kit is damaged, by typing 'y'es. If you
do, don't blame me if something goes wrong. I advise you to type 'n'o
