As the missing tcl libraries aren't missing but were packed with
the app and installed in the user's home directory, can't the script be
altered so that the 'wish' test fails and the BDT-installation of TCL-TK is
used--as the script not very robustly (because it didn't take into
account versioning) intended in the first place?
Or am I misunderstanding some essential thing?
