Go To: http://ftp.gnu.org/pub/gnu/
Browse for the app you are in need of, say wget, since this did not come on Mac OSX.
Download the tarball then unzip and install
1 2 3 4 5 | tar -xvzf wget-1.11.4.tar.gz cd wget-1.11.4 ./configure make sudo make install |
p.s. you may need tar also, if not, Stuffit will unzip, and make is included in the Apple XCode (~1.1GB)
