When I upgraded to the Mac Book Pro, the Post Trackback script, that is used to send trackbacks from within ecto, stopped working. The mgrep scripting addition, was only compiled for PPC, so script fails to run on an Intel Mac.
I finally got around to removing the dependancy on this addition. Now this script runs a perl script with the do shell script command, to to the parsing.
The new version of the script can be found here.
