MySQL gem

Where is the 2.7.3 and greater version of the MySQL gem for
non-Windows installs?

It seems to be developed by the guy who has tmtm.org

I checked his site at http://tmtm.org/en/mysql/ruby/, and the latest
version is 2.7.3, but there is no Linux version available via the
mirrors.

Any of you guys get mysql offered as a gem update, but the only newer
versions available are for Windows?

Has upstream development on this died? I tried emailing the author,
but I don't speak Japanese.

Cheers,
