Weird. Did you build both versions of git from source (that is, there's no question that the OS X one is a hacked-up Apple git or something)?

Presumably it's some incompatibility in the shells used. What does:

  head -1 "$(git --exec-path)/git-filter-branch"

say about the shell in use on each system? Does running that shell with "--version" report anything useful?
