The GNU version of find has some nice features (like -readable). You can install it with MacPorts using sudo port install findutils. However, this installs it as gfind. There are some references on the web to using the +with_default_names variant to avoid this, but a quick check of port variants findutils reveals that there is no such variant. This is intentional. The new approach is that /opt/local/libexec/gnubin/ contains symlinks with the native names. So add this directory to your path as well and you’re all set.
For more GNU goodness, check out the md5sha1sum package (for md5sum) as well as coreutils.
