Cannot install .rpm in RH 5.0

[Brenno de Winter <mailing redhat dewinter com>]

Hello,

I am using RH Linux 5.0. I try to install an RPM that installs perfectly
with RedHat Linux 4.2. All of a sudden I get this error message back?
Where can I get the correct library or what do I need to do?

failed dependencies:
        libreadline.so.2 is needed by mysql-3.20.32a-3
        linuxthreads >= 0.6 is needed by mysql-3.20.32a-3

Have a merry Christmas,

Yours,

Brenno de Winter
