The thing is, there are 3 CGI components. There is HTML generation, graph zooming, and graph generation. The first two work for me so CGI must be working. I think there is a problem with the Gentoo's munin.include for apache since it doesn't reference /munin-cgi/munin-cgi-graph/. I've filed a bug: https://bugs.gentoo.org/show_bug.cgi?id=473698 Actually, I think I just fixed it and I've updated the bug. It's a Gentoo issue. - Grant
