Another `head` program might be in the user's `PATH` if the user installed libwww-perl to another prefix that's in their `PATH` before `/usr/bin`. This problem was reported [http://lists.macosforge.org/pipermail/macports- users/2007-January/001341.html on macports-users in January 2007] and [ticket:12251 in this ticket in June 2007] and [http://www.ghostwheel.com/merlin/Personal/notes/2007/11/28/os-x-unix-and- dont-you-forget-it/ on someone's blog in November 2007] and [http://lists.macosforge.org/pipermail/macports- users/2007-December/007434.html on macports-users in December 2007] and [ticket:14093 in this ticket in January 2008]. It would be nice if there were a more-intelligible error message for this situation. -- Ticket URL: <http://trac.macosforge.org/projects/macports/ticket/14102> MacPorts </projects/macports> Ports system for Mac OS
