Tcl/Tk, incrTcl, and MetaKit in a self-contained executable (allows cross platform starkits)
Upstream tarballs are not versioned. This means that they can change at any time, and we'll have random md5sum breakages. Can we ask the upstream guys to version their tarballs ? If not, we'll have to version-tag them ourselves, but that means that tclkit will become a higher-maintenance ebuild that most likely will be lose some priority.
Too little to go on here.
