hi there,

here is a simple patch for first-setup.sh
in a nutshell:

- removed the first check for ruby.  the same check is performed
  at the end of the install process again, and IMHO it is a much
  better place to show some reminders to the user after many
  screenfuls of rsync flew by.

- a low hanging optimisation for setting platform=

- moved the platform overriding above the platform == unknown check
  because just uncommenting the line will not work, the script will
  exit a couple lines above

- if the uknown platform is considered an "Error", exit should return
  non-zero :]

have a nice day
