Hello,
I have a problem while installing ns2-allinone package, when I have downloaded this file and install it on my ubuntu 12.04 with ./install command I have got this message on my terminal to edit the path inside the .bashrc file.

You MUST put /home/j0k3r/ns-allinone-2.35/otcl-1.14, /home/j0k3r/ns-allinone-2.35/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 /home/j0k3r/ns-allinone-2.35/tcl8.5.10/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-2.35; ./validate

For trouble shooting, please first read ns problems page
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive
for related posts.

But when I have fixed this path inside .bashrc, I am getting this error message when ever I used to open my terminal

j0k3r@j0k3r:~$ source .bashrc
bash: export: `/home/j0k3r/ns-allinone-2.35/lib,': not a valid identifier
j0k3r@j0k3r:~$
