Attempting to locate a machine to test on...

Preparations

• How to tell what version of OS/X you're on.
• Dependencies
  • Subversion
  • m4 - apparently ships with OS/X, but might be old and buggy. Also might be named "gm4" for GNU m4.
  • Python 2.5+ (comes with the OS? Might be too old though)
  • xz - has binaries for 10.4 and later
  • find - probably a BSD find, hopefully new enough to have -print0
