HELP: test-suits don't work!

[Dan Li <dli@CS.Stanford.EDU>]

Hi, Folks.

I had ns installed but it doesn't pass test-all. The error is about
Invalid command name "Simulator". I grep'ed and found no definition of
Simulator. I re-unpacked the ns-2.0 package and diff'ed. The only
change I made to the ns source tree is "TclCL_VERS" from 1.0b3 to 1.0b4 
in file "configure". 

"Simulator" seems the main class of the whole package. What could go wrong
with it? Or with some utilities in my Linux-2.0.27 system. I installed
every component listed in ns-2 website, tcl7.6/tk4.2, otcl0.96,
tclcl1.0b4, etc.. But none of the patches.

Your insight is highly apprciated! The actual print out:
