I think the only reason this may be worth doing in Mathematica is that
the sorting and selection of the input files perhaps requires some
nontrivial processing. Assuming you have already solved that problem,
here is a simple way to proceed.

Calling this a Mathematica solution is perhaps cheating, but here it
is anyway:

coalescePDF[inputFiles_?ListQ, outputFile_?StringQ] :=
 If[FileExistsQ[outputFile],
  Print[outputFile <>
    " already exists and has not been overwritten"],
  Run["/System/Library/Automator/Combine\\ PDF\\ \
Pages.action/Contents/Resources/join.py --output " <> outputFile <>
    " " <> StringJoin[Riffle[inputFiles, " "]]]
  ]

The input filenames are passed to this function as strings in the list
inputFiles, and the desired output file name is the second argument.
So you would call it like this:

coalescePDF[{"picture1.pdf","picture2.pdf"}, "output.pdf"]

Just in case the line breaks are ambiguous when this gets posted, make
sure the string in the path name reads as one line containing
"Combine\\ PDF\\ Pages.action"
That's an Automator action that comes with OS X, so it's perhaps
better than using LaTeX or ghostscript etc., although I'm sure you
have those installed too.

Jens
