The command has been installed with the prefix 'g'.
If you do not want the prefix, install using the 'default-names' option.
If you need to use these commands with their normal names, you
can add a "gnubin" directory to your PATH from your bashrc like:
PATH="#{opt_prefix}/libexec/gnubin:$PATH"
Additionally, you can access their man pages with normal names if you add
the "gnuman" directory to your MANPATH from your bashrc as well:
MANPATH="#{opt_prefix}/libexec/gnuman:$MANPATH"
