Problem with tar and install-Clam-0.94.2-SA-3.2.5

[Paul Welsh]

Hi all

I'm sure this is a newbie error but I'm having trouble with tar.  When I 
extracted the MailScanner-4.74.16-1.rpm.tar.gz file, I found that "tar xzvf" 
gives me an error - says it's not in gzip format.  However, "tar xvf" works 
fine.

When it comes to extracting install-Clam-0.94.2-SA-3.2.5 however, I get the 
usual "gzip: stdin: not in gzip format" but when I try tar without the z 
option I get:

# tar xvf install-Clam-SA-latest.tar.gz
install-Clam-0.94.2-SA-3.2.5/
install-Clam-0.94.2-SA-3.2.5/perl-tar/
install-Clam-0.94.2-SA-3.2.5/perl-tar/Data-Dump-1.08.tar.gz
install-Clam-0.94.2-SA-3.2.5/perl-tar/ExtUtils-ParseXS-2.18.tar.gz
install-Clam-0.94.2-SA-3.2.5/perl-tar/version-0.7203.tar.gz
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Error exit delayed from previous errors

If I go into install-Clam-0.94.2-SA-3.2.5/perl-tar I see:

Data-Dump-1.08.tar.gz
ExtUtils-ParseXS-2.18.tar.gz
version-0.7203.tar.gz

and I can extract the first two files using tar xzvf, but when I try "tar 
xzvf version-0.7203.tar.gz" or "tar xvf version-0.7203.tar.gz" I get the 
following error.  Any ideas?  I'm running CentOS 5.2 with kernel 
2.6.18-92.1.22.el5 and GNU tar 1.15.1.
