James R. Van Zandt uploaded tclx8.0.4 to frozen and unstable today, with this in the changelog:
* Replaces tclx76 which is no longer installable (closes:bug#56541) * Satisfy tclx dependency so emacspeak can be installed (closes:bug#59099) That takes care of my concerns with tclx76, so I've installed tclx8.0.4 and removed tclx76. The versions of tclx76 that I removed are still available in slink, so I didn't put any in project/orphaned. Richard Braakman
