Help with Download

[Moon, John]

I have downloaded http://stein.cshl.org/WWW/software/CGI/CGI.pm.tar.gz (to
pc then ftp to Unix as binary to directory when I want to install ) but am
not familiar with the tar processor... When I tried :

SUN2>tar xvf *.tar

got the following message ...

tar: directory checksum error

Please help with "tar" (and/or any other suggestions)
