notes "
This port previously installed itself without a g* prefix, thus overshadowing\
system binaries such as grep, fgrep, and egrep. The port is now changed so that\
it does install with a g* prefix, like other GNU ports. This means that you'll\
now find GNU grep at ${prefix}/bin/ggrep. If you dislike typing ggrep, you can\
create a shell alias or you can add ${prefix}/libexec/gnubin to your PATH,\
wherein non-g* prefixed symlinks are installed. In other words,\
${prefix}/libexec/gnubin contains GNU binaries without any prefix to the file\
names, so you can type grep and get GNU grep just as before.
