MtrOnOSX

mtr is a nice network diagnostic tool a la traceroute (just on steroids, with tons of more useful options). It's available with a curses and a GTK interface.

The build seems to need automake and autoconf (just use Fink).

With the original mtr 0.69 sources, the build will break with an error like the following:
 source='dns.c' object='dns.o' libtool=no \
 depfile='.deps/dns.Po' tmpdepfile='.deps/dns.TPo' \

The solution can be found in this posting (cache) on the NetBSD tech-pkg mailinglist, or just apply the following patch:

(this seems to be a common problem with MacOS X ports, sometimes adding -DBIND_8_COMPAT to the CFLAGS might help, too)

With this change, mtr builds without any further problems:
 > ./configure --without-gtk --with-gtk-prefix=/neverthere --prefix=/usr/local 
 > make
 > sudo make install
