curious. Maybe something up with the feed?
Its showing up here on my feed but i'm using a snapshot release.
You can always do a manual install using my thread. Both the opkg and manual install require some SSH usage as you cannot deploy out of box without assuming some defaults and so you must do some config on the way. The differance between the opkg versions and the manual is opkg only takes the stable releases and repacks them for OpenWrt. Manual version lets you use the more up to date feeds (which are at this point fairly stable) but aren't really "stable" releases so aren't allowed under opkg rules.
