This is because tcl can't find the libraries.  Supposedly,
someone told Tcl, during compilation probably, that it 
would find its library files in /usr2/opt/apps/lib/tcl7.6 or
somesuch.

You can fix this by first finding those libraries (a 
find / -name init.tcl -print should do the trick), then
setting the environment variable TCL_LIBRARY equal to the
path where you found that file.  The same should probably
be done for Tk.
