I bought the frame and built it up myself.
Unfortunately, few women's bikes come equipped with Campy Chorus or Record (Specialized no exception) and the total costs of a self-build ends up costing much more than buying a whole bike with comparable parts.
On the positive side, I didn't care for the stock wheels, saddle, or handlebars so I was able to build up my Ruby with exactly what I wanted.
P.S. Frame-only options:
For 2008 Specialized added the module-only option of the Ruby-Comp for about $1300. In 2007, when I bought my frame, all they offered was the S-Works for $3300.
