I was able to reproduce the "could not create "normal" interpreter"
behavior after removing "init.tcl" from the Tcl library directory.
Unfortunately, it seems that this breaks Tcl badly enough that it's
not capable of returning a useful error message :-( --- the fact that
our code doesn't make any attempt to print the interpreter result
is probably Not Good, but when I changed it to do so, I still didn't
get anything but an empty string ...

So the short answer is "install Tcl per its directions".
