parsec input size mktar

[RaoKarter]

1. I downloaded simlarge inputs for benchmarks and I change the inputsize line in parsecmgmt tool when making tar balls. However, for benchmarks that do not have an input folder, mktar fails. For example: streamcluster takes simlarge input as a string.
2. Out of the ones that could be built, some fail to run on manifold.
   bodytrack: ./runme.sh: line 3: bin/bodytrack: not found (although it is there inside the tarball)
   vips: ./runme.sh: line 3: bin/vips: not found (although it is there inside the tarball)
   facesim: Storytelling/output directory cannot be created (although the folder has write privileges)
   barnes, fmm, cholesky, raytrace: ./runme.sh: line 3: bin/run.sh: not found
