Happens about once a decade, so nothing much to worry about.  But the 
short answer is the install the -dev packages matching those packages 
you already have installed.

[Tcl/Tk 8.6 is in beta, and has had no progress for 18 months.]

Following the current manual is likely to be more useful to them. 
Let's see: Appendix A:

Remember that some package management systems (such as RPM and deb) 
make a distinction between the user version of a package and the 
development version. The latter usually has the same name but with the 
extension `-devel' or `-dev': you need both versions installed.

The tcltk package needs Tcl/Tk >= 8.4 installed: the sources are 
available at http://www.tcl.tk/.
