Hi Chris

You need an inner query that selects the closest line segment and use that 
geometry in the shortest line query 
Select shrtest line(p.the_geom,nearestgeom.thegeom) from
Points p,
Select  a.*, st_distance(a.the_geom, b.the_geom) as dist from roads a,points b 
order by dist asc limit 1) as nearestgeom

Hope this is readable as sending from phone.
