Since Bukkit is going to replace hMod as the creator has decided to stop updating hMod, a Bukkit version has been created for Minequery. It basically has the same functionally as the hMod version. The hMod version of the plugin is no longer supported.
Thanks to Blake Beaupain (blakeman8192) for creating the Bukkit version of Minequery and getting it started.
More information about Minequery can be found on Minestatus.
