MySQL on RHEL4

[Nitin Mehta]

Hi,
 
We're trying to upgrade our existing MySQL 5.1.26 to MySQL 5.1.68 but the 
installation gives error:
 
libc.so.6(GLIBC_2.4) is needed by MySQL-server-community-5.1.68-1.rhel5.i386 
rtld(GNU_HASH) is needed by MySQL-server-community-5.1.68-1.rhel5.i386 
 
Now, GLIBS2.4 is not available for RHEL4 and MySQL 5.1 and 5.5 are supported on 
RHEL4 as per this: http://www.mysql.com/support/supportedplatforms/database.html
 
Any ideas?
 
Regards,
Nitin
