export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB

# TCL_LIBRARY
TCL_LIB=/your/path/ns-allinone-2.31/tcl8.4.14/library

export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH
XGRAPH=/your/path/ns-allinone-2.31/bin:/your/path/ns-allinone-2.31/tcl8.4.14/unix:/your/path/ns-allinone-2.31/tk8.4.14/unix
