Error in installing postgresql-7.1.2

Hi,
I am using RedHat-6.2. I was using Postgresql-7.0.3
and I was getting the error "Sorry, too many clients
already" frequently though the no. of users connected
with the database are 3 to 4. So, I tried to install
Postgresql-7.1.2 and downloaded the following rpms.

1. postgresql-7.1.2-4PGDG.i386.rpm
2. postgresql-devel-7.1.2-4PGDG.i386.rpm
3. postgresql-server-7.1.2-4PGDG.i386.rpm
4. postgresql-jdbc-7.1.2-4PGDG.i386.rpm

When I started installing
'postgresql-7.1.2-4PGDG.i386.rpm' it ended up with an
error "failed dependencies:
libcrypto.so.0 is needed by postgresql-7.1.2-4PGDG
libpq.so.2 is needed by postgresql-7.1.2-4PGDG
libssl.so.0 is needed by postgresql-7.1.2-4PGDG "

I don't know where to find these lib files. Where I am
wrong? Please help me. Thanks in advance.
