RPM won't install

I'm running Mandrake 7.2 and trying to upgrade postgresql to 7.1.  The
installed version has the timestamp bug, so I must upgrade.  RPM install
said I needed libc.so.6, which is on my system.  So I installed rpm with
--nodeps to force it to install.  However, running Postgresql complains
that libc.so.6 is incorrect version, and requires "GLIBC_2.2".  I
installed from the RedHat 7.1 RPM binary.  Any suggestions as to what is
going on?

Help would be GREATLY appreciated, as I am on a time crunch on this.
Anybody know what version postgresql is in Mandrake 8.0?  Maybe I should
just upgrade my server now.
