[expert] rpm refuses to upgrade

[Gavin Clark]

rpm won't let me install an rpm I got from cooker:

# rpm -ivh mirrordir-0.10.44-3mdk.i586.rpm
only packages with major numbers <= 3 are supported by this version of RPM
error: mirrordir-0.10.44-3mdk.i586.rpm cannot be installed

I then downloaded a newer version of rpm but I got the same error message
when I tried it upgrade that!

how do I fix this?

Thanks

Gavin
