For layout machine comparison, I'd go with DXF instead of PDF - which is 
an open-source vector format that can be read by most Gerber 
editors/viewers, and is generated by all layout systems I know of:

Load the production Gerber file superimposed on a DXF file into a Gerber 
Viewer, and in a minute you can visually observe any discrepancy.
