I was just looking through distfiles mirror, found more than 40 index.htmls and discovered naim ebuild creates them. This is (probablly) because naim-0.11.15.9 doesn't exist at the source site but the SRC_URI doesn't return an error (instead, you will be displayed the page named 'index.html'). Naim-0.11.6.4 was released last month and I think we could put it into Portage and remove naim-0.11.15.9. It seems that index.html will be created daily, so I suppose the sooner the better.
I've added 0.11.6.4 -- but I don't know if it's okay to remove 0.11.5.9, could the SRC_URI be set as nothing?
Thanks :) SRC_URI is MUST variable according to EBUILD HOWTO sowe cannot set it to "", but we could set it to SRC_URI="mirror://gentoo/${P}.tar.gz"because Gentoo mirrors already have naim-0.11.5.9.tar.gz(If they don't, we need to place it on distfiles-local at dev.gentoo.org). If you don't feel lile removing naim-0.11.5.9.ebuild, please set it so.
Removed 0.11.5.9 -- raker, if there's a problem with this let me know.
