# -Q1P- Why do I get invalid command name when I start wish?

    From: -I- Questions on building Tcl and friends on your system

    A1S. Often when folks trying to build a new version of wish get done
    and try to start it up, they get errors such as:

    >$ /projects/xopsrc/wishx3.6a
    >Error: invalid command name "tk_bindForTraversal"
    >invalid command name "tk_bindForTraversal"
    >    while executing
    >"tk_bindForTraversal Entry"
    >    (file "/projects/xopsrc/Tclsrc/v7/lib/3.6a/tk.tcl" line 98)
    >    invoked from within
    >"source $tk_library/tk.tcl"
    >    invoked from within
    >"if [file exists $tk_library/tk.tcl] {
    >            source $tk_library/tk.tcl
    >        } else {
    >            set msg "can't find $tk_library/tk.tcl; perhaps you "
    >            append  ..."

    The _real_ problem is, in all likelihood, that they do not have
    something either configured or installed properly.  If the command name
    is really valid, then auto_path isn't set right, an external variable
    pointing to the directories is overriding the default location, or things
    didn't install.
