[ns] ns-2.28 Installation Error:extra qualification 'SctpAgent::' on member 'DumpSendBuffer'

[Bringo Shawn]

Hello.
I am installing ns-2.28 on fedora 9. I faced the error:
./sctp/sctp.h:630: error: extraqualification 'SctpAgent::' on member 'DumpSendBuffer'
make: *** [trace/trace.o] Error 1
I found a solution posted at  http://mailman.isi.edu/pipermail/ns-users/2006-September/057325.html. The solution was to remove the extra qualifier i.e 'SctpAgent::', but then make gave some other error in the file god.h, so I removed it's extra qualifier too that was probably vertor:: and again executed the make command and now there are the following errors:
...
