[Haskell-cafe] Is protocol-buffers package maintainer reachable?

Hello Cafe! I am using protocol-buffers and hprotoc packages but they fail to compile with recent GHC due to trivial errors. Hackage names Christopher Edward Kuklewicz as their maintainer. I've sent him patches more than a month ago but neiter they were applied nor I got any response. It's quite inconvenient to keep patched versions all the time. Does anybody know if he is still interested in maintaining those packages? Is it possible to contact him? And what should I do if he is unreachable? Thanks!
