CBEgit has 89 files in /opt/dtbld/libexec/git-core of the same size and SHA1 hash. By installation, they should just all be hard links. By the time the package is installed via pkgbuild, the files are all separate files. This makes the CBEgit package absolutely huge, since each binary is 6MB, so 450MB. I can work around this by taking the package install directory and redo the hardlinks before creating a pkg file, but this is overhead that is unnecessary.
