Bug #39617 5.0.68 gives error unpacking on Solaris 9

Description:
Unpacking 5.0.68 on Solaris 9 gives an error (mysql-5.0.68-solaris9-sparc-64bit).

tar -xvf mysql-enterprise-gpl-5.0.68-solaris9-sparc-64bit.tar
...
tar: A lone zero block at 403260

How to repeat:
Simply gunzip and then untar the file on Solaris 9:

shell> gunzip mysql-enterprise-gpl-5.0.68-solaris9-sparc-64bit.tar.gz

shell> tar -xvf mysql-enterprise-gpl-5.0.68-solaris9-sparc-64bit.tar

tar: A lone zero block at 403260

Suggested fix:
If you untar and then retar the files, and then untar, the error goes away.  Perhaps an end-of-block is being written improperly to create the tarball.

Note that all files are extracted properly, so it is okay to simply ignore this warning/error messsage when extracting MySQL.

I've re-tested this with 5.0.85 on Solaris 9, and this bug no longer exists.

Furthermore, I wanted to note that this could also be a result of using the Solaris 'tar' as opposed to the GNU 'tar'.

In fact, the MySQL Manual recommends to use GNU tar instead of Solaris tar even when installing MySQL on Solaris (as there are some other known problems):

http://dev.mysql.com/doc/refman/5.1/en/solaris-installation.html

Closing as "Not a bug", because
1) note of 2008-Sep-23 says "all files are extracted properly", and
2) note of 2009-Aug-27 says it happened using Solaris tar,
   whereas the manual recommends to use GNU tar.
