Dear sir:
	I have some problem about ns (2.0a17-current).
I have already compiled ns, but when i run the test program
(test-all), it can't work correctly, and show some message like 
following text 

=====================================================================
columbus:/home10/user/ytliu/ns/ns-2.0a17-current/>test-all
tahoe1 tahoe2 tahoe3 tahoe4 no_bug bug reno1 reno renoA reno2 reno3

Running test tahoe1
invalid command name "Simulator"
    while executing
"Simulator create _o2"
    ("eval" body line 1)
    invoked from within
"eval $className create $o $args"
    (procedure "new" line 3)
    invoked from within
"new Simulator"
    invoked from within
"set ns_ [new Simulator]..."
    (procedure "_o1" line 3)
    invoked from within
"$self next"
    (procedure "_o1" line 6)
    invoked from within

    invoked from within

    (procedure "TestSuite" line 22)
    invoked from within

    (file "test-suite.tcl" line 1092)
