git-annex/Build/Configure.hs
Joey Hess 82617b92e9 move thirdparty program installation for standalone bundle into haskell program
This allows it to use Build.SysConfig to always install the programs
configure detected. Amoung other fixes, this ensures the right uuid
generator and checksum programs are installed.

I also cleaned up the handling of lsof's path; configure now checks for
it in PATH, but falls back to looking for it in sbin directories.
