rtl_tcp no longer works on macos 10.15 via macports
rtl_tcp no longer works on MacOS 10.15 (catalina) installed via macports. I was able to install an old port in order to get it to work. It appears that the code which sets up the tcp server contains a bug. The other executables in the package appear to work correctly.
Output from running rtl_tcp with no arguments:

Use the device argument 'rtl_tcp=127.0.0.1:1234' in OsmoSDR (gr-osmosdr) source
to receive samples in GRC and control rtl_tcp parameters (frequency, gain, ...).

I am not sure which commit introduced the bug but it is between be2e4f89 and d794155b.
