Hmm, I'm not sure that the other projects would need an update. In Tcl 
world, there is the concept of stub libraries, an extra level of 
indirect linking provided by both the Tcl and Tk core. If the extensions 
link to the stub library (the standard way), they can be loaded into any 
later version of Tcl and do not directly depend on libtcl or libtk. If 
the extensions link directly to libtcl, they are either broken or very 
special (providing one's own interpreter, doing nasty stuff with 
internals etc.)
