nc is replaced by netcat on some machines, in which case stap-start-server will
not work.

Just pushed a fix which will use nc or netcat, depending on which is found.

the netcat command doesnt allow the -d option. Can we remove the -d?
/systemtap # netcat -ld 65000 
netcat: invalid option -- 'd'
netcat -h for help

The -d option tells nc not to read from stdin. Is there a similar option for netcat?

I dont see any option with netcat that would do the same thing. Will it be
alright to just remove the -d in case of netcat?.

I've removed -d in favour of redirecting stdin from /dev/null.
