media-gfx/openvrml moved from portage to sunrise in 2007, but has no bug. Thus, opening one now... This is now in the sunrise overlay. You can find it at: http://overlays.gentoo.org/proj/sunrise/browser/reviewed/media-gfx/openvrml/ For the package removal from portage see bug 137775.
It seems that this package is no longer in Sunrise.
