mktap doesn't bind ports, twistd does. The point is that you run
`mktap' as the user who you ultimately want the process to be run as,
and if you need root privelages to bind the ports it uses, run
`twistd' as root. It'll drop privs right after it binds.

That's odd. Can you check the output of `mktap --help'? Also mktap

If you're using the Ports Twisted package, maybe the problem is with
it? If you're using the tarball, the manpages are located in doc/man.

Run mktap as nobody (or, once you figure out what the problem is, with
the --uid option), and twistd as root.
