You have installed libwww-perl with its helper "HEAD" program, which has replaced your OS's unrelated "head" program because Mac OS X's filesystem is case-insensitive. Please restore the proper "head" program into your /usr/bin from your backups or from another machine with the same OS version, or reinstall Mac OS X to get it back. To avoid this, don't install libwww-perl with its "helper" scripts. If you install p5-libwww-perl using MacPorts, it will not include these helper scripts so you will not have this problem.
