Many files in the tcldebugger package use the '-col'
option to the grid command. In more recent versions of
Tk, this generates an error:
ambiguous option "-col": must be -column, -columnspan,
-in, -ipadx, -ipady, -padx, -pady, -row, -rowspan, or
There are also many references to the tkPriv() array,
which has been replaced by the tk:: namespace.
The attached patch fixes both of these problems.
