#!/bin/bash

grep -i "OpenSolaris" /etc/release > /dev/null
if [ $? == 0 ] ; then

  # gcc
  pkg install SUNWgcc

  # gmake
  pkg install SUNWgmake

  # cmake
  pkg install pkg:/SUNWcmake

  # ncurses
  pkg install SUNncurses

  # readline
  pfexec pkg set-authority -O http://pkg.opensolaris.org/pending/ pending
