Well, we have a policy that we will only add ebuilds to the prefix tree 
if they are in the gentoo-x86 tree. There are many reasons for this, the 
main one is developer time. Also, we "auto-sync" from gentoo-x86 tree 
and have no infrastructure up to auto-sync from $overlay - nor want to 
to be honest.

Here is my suggestion. We have a separate layman file that we can update 
to include overlays that are prefix specific. So, I would suggest that 
you setup another overlay on github or similar hosting place. This new 
overlay would have those ebuilds that you have ported to prefix. You 
won't be able to use ecopy for these ebuilds because that pulls from 
gentoo-x86. However, ecopy is just a wrapper for eapify (and others, 
look at the ecopy script - it is pretty well commented now)

So, in a nutshell.

-checkout/clone the ruby overlay (you can't use layman to do this in prefix)
-Use ecleankw and eapify to port the ebuilds - (eapify is a best effort 
script and won't necessarily do everything for you)
-Test them on your prefix
-Commit them to a separate hosting place (ie. github)
-Let us know the address, we will update the layman file for you and 
then Prefix users can use Ruby 1.9.x

Feel free to get help porting in #gentoo-prefix on freenode or on this 
mailing list.

Thanks,
