Officially your patch has to go through the "Library submission" process:


Since you already have a ticket the only thing left to do is convert
your patch to a darcs patch and send a proposal to the libraries list.

To save you some work I've created and tested the attached darcs patch
that adds the single line "deriving Eq" to Control.Concurrent.Chan.

If you want to create your own patch you need to get the GHC sources
(which include the libraries). See:

Be sure to also include a deadline in your proposal. I think one week is enough.
