Yep, that should do it.  Deactivating MacPorts grep, sox build fails - activating MacPorts grep fixes the build on 10.7. I have other things installed that get pulled in (gsed, otools) so this is not a buildbot, but grep should do the trick.

Is sox building on the 10.5 and 10.6 buildbots? If so, don't know how / why. 

Can I suggest this patch be applied to all systems <= 10.7? They probably all need the new grep to build it.

Best,

Ken
