Centos 5.5 and Postgres 9.0.beta3 install errors

Dear all,

Can anyone help me with the errors I seem to be having installing the
latest Postgresql 9.0 beta 3 rpms from the PGDG-9.0 repository on Centos
5.5?

I am having dependency issues:

Error: Missing Dependency: libpq.so.4 is needed by package
postgresql-libs-9.0-beta3_1PGDG.el5.i386 (pgdg90)
Error: Missing Dependency: libecpg.so.5 is needed by package
postgresql-libs-9.0-beta3_1PGDG.el5.i386 (pgdg90)
Error: Missing Dependency: libpgtypes.so.2 is needed by package
postgresql-libs-9.0-beta3_1PGDG.el5.i386 (pgdg90)

I've tried installing postgresql-libs from the original Centos
repository which provides all of the above files however when trying to
update the packages to PG 9.0 I continue to get these errors.

Thank you,
Tom Robst
