When searching for ntop failure to build I could only find http://trac.macosforge.org/projects/macports/ticket/14308 which does not apply in my case, but whose author mentions a ticket #13648, with - presumably - a fix, which ticket I could not find: http://trac.macosforge.org/projects/macports/search?q=13648&noquickjump=1&ti...
