This error message comes from Tcl, in file =E2=80=98auto.tcl=E2=80=99, proc=
edure
=E2=80=98tcl_findLibrary=E2=80=99.

We=E2=80=99d need to find where the call comes from and hard-code a search =
path
in there maybe?

I just did =E2=80=9Cimport tkinter.=E2=80=9D

Yes.  That wouldn=E2=80=99t help for Python though, where we need to hard-c=
ode
the search path somehow.

I don=E2=80=99t think it would help because Python finds Tcl and Tk anyway.

Thanks,
