Hi Joel,

This is typical behavior on some BSD-like systems that don't support
select(2) on BPF file descriptors.  As a workaround, you can try running
tcptraceroute with the --no-select command line argument, which will force
it to check for new data without first consulting select(2) to see weather
or not it's available.  If that works for you, can you please send me the
output of "tcptraceroute -dv", "uname -a" and, "gcc -E -dM - </dev/null" on
your system?  Armed with that data, it may be possible to write an autoconf
check such that --no-select is the default behavior on MacOS X in the
future.

Thanks!
