Why do you need that?  In particular, why do you need
.../library/tcltk/libs in the PATH?

Both the README and the FAQ already tell you to put the Tcl/Tk DLLs in
the your path, so why does the information need to be repeated?
Unless something went wrong in your Tcl/Tk installation, they will be in
your path, so why put them in a second time?

Where is the bug?
