[ns] invalid ommand name "AddrParams"

[Faisal Aslam]

Hi,

When I run SPAN (http://pdos.csail.mit.edu/~benjie/span/span_ns.html) then
it gives me following error.

----
:invalid command name "AddrParams"
while executing
"AddrParams proc addr2id addrstr {
if [Simulator hier-addr?] {
set addressObj [[[Simulator instance] get-AllocAddrBits ""] \
get-Address]
return [$addr....
----

PATH and LD_LIBRARY_PATH variables look fine. I have installed tcl8.3.2,
tk8.3.2 ,tclcl-1.0b10 ,otcl-1.0a6 and ns-2.17b.

Any clues?
