I'm new to Ruby on Rails, and I'm in the process of setting it up on my OS X system. Most guides seem to recommend using MacPorts to install Ruby and RubyGems, then using RubyGems from there on to install gems.

Doing the following: validates_presence_of :song_rep_xyz, :message => "can't be empty" ... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly.
