Thank you John:

The operating system is OS X Tiger which should have tcltk installed.  I
went ahead and did a separate install of tcltk AquaBI 8.4.10.0, but the
error still persists when I try to load the widgetTools.  Tiger and the more
recent tcltk releases may be loading tcltk in a different directory.  Does
anyone have a solution?

Cheers,

You need to install the Tcl/Tk library as well
(http://www.tcl.tk/software/tcltk/).
