Some of them will be from the stock Red Hat repositories, and some will 
be from the PGDG repository.  I haven't used that repository, and I 
haven't done much on an RPM-based system for a while so I can't give you 
any more specific information.

It's possible - but very tedious and difficult - to install a package 
with a large dependency tree entirely by hand.  I *have* done this 
myself in the past, and I recall a few cases where it literally took two 
or three hours to get everything installed to support the specific 
package I started out trying to install.  This is why tools like yum 
were developed;  they do the work of checking through the list to see 
what's required, and where it can be installed from.

This isn't specific to Postgres;  it's how the underlying OS package 
system works.  You may want to see if someone in your office has more 
experience installing packages on RHEL with yum and ask them to give you 
a hand.  You've got several issues around yum's basic operation that you 
need to fix, and local network/systems admins should know enough about 
your setup to help a lot faster.
