8.02 rpm error

I have a customer with the following error.

rpm -Uvh *.rpm
warning: postgresql-8.0.2-1PGDG.i686.rpm: V3 DSA signature: NOKEY, key 
ID 748f7d0e
error: Failed dependencies:      libpq.so.3 is needed by postgresql-contrib-8.0.2-1PGDG      libecpg.so.4 is needed by

postgresql-libs-8.0.2-1PGDG Suggested resolutions:      rh-postgresql-libs-7.3.8-2.i386.rpm
 

Has anyone else experienced this ? Is there a solution?
