There are innumerable free implementations of barcode generation. I don't
know of a wrapper around one of the libraries, but it should be pretty
simple to implement. Perhaps this library would be a good start:
http://sourceforge.net/projects/zint

Write a C extension and you're good to go. Once you have the output in some
format, you should be able to turn it into a PDF one way or another (e.g.
RMagick).
