I checked the Cent OS 7 iwidgets package: it is compatible with Tcl8.5
and not Tcl8.6, but you have Tcl8.6. It may be the case that your Itk
may also be compatible with Tcl8.5.

Cent OS also has tcl8.5 and you can try to install it (before doing so,
see the alternative below). Then you can repeat the sequence:

tclsh8.5
package require Tk
package require Itcl
package require Itk
package require Iwidgets

But it may be the case that you will also need to install a lower
version of Itcl (there is itcl-3.4-10.el7.x86_64.rpm).

Alternatively, you can upgrade to Cent OS 8, where iwidgets and itk are
compatible with Tcl8.6 (I checked).
