These kinds of errors almost always mean you are missing the *development*
packages for the program you are trying to compile. Try this:

 apt-cache search tcl tk | grep dev

You will see a whole list including for example 

tcl8.0-dev - Tcl (the Tool Command Language) v8.0 - development files
tcl8.3-dev - Tcl (the Tool Command Language) v8.3 - development files
tcl8.4-dev - Tcl (the Tool Command Language) v8.4 - development files
tk8.3-dev - Tk toolkit for Tcl and X11, v8.3 - development files
tk8.4-dev - Tk toolkit for Tcl and X11, v8.4 - development files

So you might try installing the 8.4 versions of these -dev packages before
running ./configure.
