Help please!

Hi, My question is the following one: I have downloaded several times the file 
mysql-3.23.39.tar.gz, I decompress using
shell> gunzip < mysql-VERSION.tar.gz | tar -xvf -
and it always finishes with the following error: x 
mysql-3.23.39/sql-bench/Results-win32/ATIS-access_odbc-win98-cmp-Access, mysql, ytes, 
2 covers blocks to tar: directory checksum error
Why pass this? What is wrong?
Thank you
Ernesto
