Fixed --includepkg not working

The process builder works by taking in a list of arguments.
It probably thinks that 2 dashes (--) means that the switch shouldn't
have an argument and that 1 dash (-) means that an argument should follow.
This is probably why '-n package' worked and not '--includepkg package'.
