PG 7.2 install on RH 7.0 dependency errors

Hello,

Quick question ... when trying to upgrade an existing PG 7.1.3 system on
RH7.0 I get the following dependency errors.
I have installed / upgraded to 'openssl-0.9.6-9.i386.rpm' and
'krb5-libs-1.2.2-12.i386.rpm' thinking it might help (no change). There
are no databases to be unloaded / reloaded.

Any suggestions to help would be greatly appreciated !

Thanks.

David.
