Title: Added support for older osx versions with -mmacosx-version-min

Building by default on Mavericks (and maybe 10.8) removes older OSX support. The executable exits immedaitely with
"illegal instruction: 4"
Specifying -mmacosx-version-min means old versions are supported.

Note: I could only successfully build perforce (before and after changes)
