Hi, 
  I'm a student from the University of Tokyo and I wish to use ns to
simulate my research. I succeeded to install the previous version,
ns-2.0a16 but when I tried to install the new version, ns-2.0b17, I
failed. It seems that the trace file has changed and the declaration
of "TracedVar" cannot be found. The make result is like below(some has 
been omitted):

c++ -o connector.o -c -I../Tcl-1.0a6   -I/home/balim/src/ns-2.0b17/../otcl-0.96 -I/home/balim/src/ns-2.0b17/../tk4.2/generic -I/home/balim/src/ns-2.0b17/../tcl7.6/generic   -I. -DNEED_SUNOS_PROTOS -DUSE_SHM -DHAVE_LIBOTCL0_96 -DHAVE_OTCL_H -DHAVE_LIBTK4_2 -DHAVE_TK_H -DHAVE_LIBTCL7_6 -DHAVE_TCL_H  -DNO_TK -Dabort=_ABORT -O2 connector.cc

Can someone please tell me how to cope with the problem? Thanks in
advance for your great help.
