I have a script that I have been using for years. As far as I know I
did not change it. In the part that creates the Tk stuff I do have:
namespace import :::bindMultiple

This gives:
import pattern ":::bindMultiple" tries to import from namespace "" into itself while executing "namespace import :::bindMultiple" (file "/home/cecil/bin/teaTk.tcl" line 1)
invoked from within "source ${scriptDir}/teaTk.tcl"
(file "/home/cecil/bin/chooseTea.tcl" line 72)

Has there changed something in tclsh?
If the namespace import is wrong: what should it be?

That was what I also thought. But changing it to two did not help.
As far as I know the code has not been changed.
It seems that it should be something like:
namespace import PACKAGE::bindMultiple

But until now I did not manage to find the correct package.
(I must confess that I am not the most proficient searcher.)

Does anyone know which package I should use?

A google search for "tcl bindMultiple" (and forcing google to not
change it to "bind multiple" returned zero hits.

Is this possibly your own custom namespace from some other bit of code
you wrote?

That was the problem. I wrote a set of proc's that I find very useful.
So I needed tot do:
namespace import ::dcblUtilities::bindMultiple

The proc for people who like to know it:
proc ::dcblUtilities::bindMultiple {tag sequences script} {
foreach event ${sequences} {
bind ${tag} <${event}> ${script}
}
}

But why ::dcblUtilities::bindMultiple was changed into :::bindMultiple

That looks like a search/replace gone wrong.

As far as I know I did not though that file for a long time. Maybe
there where gremlins in the house. ;-)

But problem solved. :-D
