7.1 installation problem

Hi,

I'm running into problems while trying to install 7.1 beta 4 (on RedHat
Linux 7 with bug fixes applied)
I've downloaded the rpms but when I do an rpm -iv
postgres-7.1beta4-1.i386.rpm it complains about an unresolved dependency on
libreadline.so.3. I have a libreadline.so.4. Is that ok?

When I ignore dependencies and continue to install, postgres won't start
because it says: "The program /usrbin/postgres needed by initdb does not
belong to PostgreSQL version 7.1beta4. Check your installation"

Any hint would be greately appreciated.
