But to the tk *headers* exist? Perhaps you need to install the
tk8.4-dev and tcl8.4-dev packages?
peds-pc311:~/mpl> ls /usr/include/tcl8.4/
tclDecls.h tclPlatDecls.h tkDecls.h tkPlatDecls.h
tcl.h tcl-private tk.h tk-private
You also have the option of not building the tkagg backend, and using
gtk*, qtagg or wxagg.
