I don't think so, as each module within tcllib is separately versioned.

You can show the versions by either capturing the return from package 
require, or by rerunning package require at the time you want the data:

    $ rlwrap tclsh
    % package require cmdline
    1.5.2
    % set cmdline_ver [package require cmdline]
    1.5.2
    % puts "cmdline version is $cmdline_ver"
    cmdline version is 1.5.2
    %
