this indeed looks like the problem is in the test_usage() methods.
All they do is test whether the given echoping binary supports any
relevant command-line options. The testing is done by 'pinging' 127.0.0.1
and trying to parse the output for any error messages.
Apparently this hangs up on your system yor some reason. Does eg.
'echoping -C -h / 127.0.0.1' work from the regular command line?
Perhaps you have really tight firewall rules that block even requests
coming from localhost?
