I know it's not a great help, but since it seems to be a specific ActivePerl case, you could ask them for help.

I'm a user of ActivePerl myself and this never happened to me, but then again I've never tried to install this specific module.

Another good way of getting some answers would be contacting the module's author or a mailing list if it's available.

Best regards,
