I'm not sure that the graphic files are actually included twice, but some
optimization is left out when using this trick, that's for sure.

Have you tried to compress the pdf file with pdftk [1]? It should pick up
on the duplicate information, and reduce the file-size. You may need to
uncompress the file first.

If you need to build it yourself (I haven't tested it on Leopard so far,
but you may need to build pdftk yourself), you can get the required gcc
toolkit (including fortran and gcj) from http://hpc.sourceforge.net/
