it installed sucessfully but after instaling it showed the message like this


Ns-allinone package has been installed successfully.
Here are the installation places:
tcl8.4.18: /root/ns-allinone-2.33/{bin,include,lib}
tk8.4.18: /root/ns-allinone-2.33/{bin,include,lib}
otcl: /root/ns-allinone-2.33/otcl-1.13
tclcl: /root/ns-allinone-2.33/tclcl-1.19
ns: /root/ns-allinone-2.33/ns-2.33/ns
nam: /root/ns-allinone-2.33/nam-1.13/nam

gt-itm: /root/ns-allinone-2.33/itm, edriver, sgb2alt, sgb2ns, sgb2comns, sgb2hierns

----------------------------------------------------------------------------------

Please put /root/ns-allinone-2.33/bin:/root/ns-allinone-2.33/tcl8.4.18/unix:/root/ns-allinone-2.33/tk8.4.18/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put /root/ns-allinone-2.33/otcl-1.13, /root/ns-allinone-2.33/lib,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to your X libraries
into LD_LIBRARY_PATH.
If you are using csh, you can set it like:
setenv LD_LIBRARY_PATH <paths>
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=<paths>

(2) You MUST put /root/ns-allinone-2.33/tcl8.4.18/library into your TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.


After these steps, you can now run the ns validation suite with
cd ns-2.33; ./validate
