Problem in running debug demo.ecl

sirs,
i am a new learner of Eclipse prolog.
i am using the latest version of the Eclipse prolog
available for Educational institiutions( No licence
needed). My operating system is Fedora core 2 (Linux)
i have installed tcl/tk latest version for running
tkeclipse.
when i compile the debugdemo.tcl given in the example
problem using tkeclipse,i obtain the following
problem.
As per the tutorial i  read on eclipse prolog , the
colouring map should obtain , but instead i get the
following errors.
Infact please tell me the way i should compile and run
the debugdemo.tcl to  get the result shown in the
tutorial.

following is the steps i performed
1.type ./tkeclipse at dollar prompt to get the GUI
menu
2.change to example directory
2.go to file menu
3. select compile
4. double click tutorial
5.select debugdemo.tcl
the program starts................
then i get the following in the output or error
messages as:
File is not open : in close(22)

*** compilation aborted
	before line 28 in the file
/home/pks/ECLiPSe/doc/examples/tutorial/debugdemo.ecl

kindly suggest whether the problem is in installation
of the prolog or some where else
