Maybe it's just me, but I fail to see what the last three posts have to do with the original question.
If the files you downloaded have the extension ".tar.gz", then they are gzipped tarballs, un zip/tar them using the following command "tar -zxvf some-file.tar.gz", the -z is for unzip.
If they are just plain binaries, BingBongWayTooLongName has it right.
If you're uncertain, try typing "file some-file", and it will try to tell you what kind of file it is.
