Where is ruby gems deb package?

I found
discuss on debian-ruby. At 1st, Daigo Moriwaki send ITP. Then "tach" said
"I have a plan to upload this package. ". But Tach is killed or forgot?

I found ay's rubygems. I have uploaded at

deb http://araki.net/deb/sid/ ./

Now I do not think to maintain ruby gem deb package officially.
