Install some packages before installing ns-2.30

Forrest Sheng Bao <http://forrest.bao.googlepages.com>

Attention: before you install ns-2 , be sure that you have installed following packages

          tcl8.4 tk8.4 tcl8.4-dev tk8.4-dev

I found that NS-2 all-in-one package is lack of the check to Xmu library when install NAM. The "configure" script of NAM doesn't check Xmu library but can generate the "makefile". Thus, you assume that everything is ok. But NAM is not installed.
On Ubuntu Linux, please also install xmu by

          sudo apt-get install libxmu-header

After the installation of NS-2 all-in-one, you will get following output

Ns-allinone package has been installed successfully.
Here are the installation places:
tcl8.4.13: /usr/local/ns-allinone-2.30/{bin,include,lib}
tk8.4.13: /usr/local/ns-allinone-2.30/{bin,include,lib}
otcl: /usr/local/ns-allinone-2.30/otcl-1.12
tclcl: /usr/local/ns-allinone-2.30/tclcl-1.18
ns: /usr/local/ns-allinone-2.30/ns-2.30/ns
nam: /usr/local/ns-allinone-2.30/nam-1.12/nam
xgraph: /usr/local/ns-allinone-2.30/xgraph-12.1
gt-itm: /usr/local/ns-allinone-2.30/itm, edriver, sgb2alt, sgb2ns, sgb2comns, sgb2hierns

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

Please put /usr/local/ns-allinone-2.30/bin:/usr/local/ns-allinone-2.30/tcl8.4.13/unix:/usr/local/ns-allinone-2.30/tk8.4.13/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put /usr/local/ns-allinone-2.30/otcl-1.12, /usr/local/ns-allinone-2.30/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
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=

(2) You MUST put /usr/local/ns-allinone-2.30/tcl8.4.13/library into your TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.

(3) [OPTIONAL] To save disk space, you can now delete directories tcl8.4.13
and tk8.4.13. They are now installed under /usr/local/ns-allinone-2.30/{bin,include,lib}

After these steps, you can now run the ns validation suite with
cd ns-2.30; ./validate
