postgresql-server-8.2.3-1mdv2007.1.i586.rpm installation problem

Hi.

I'm new to postgresql so please be patient. I'm recieving strange error
while installing postgresql from binary package. By now I installed:
postgresql-8.2.3-1mdv2007.1
postgresql-docs-8.2.3-1mdv2007.1
postgresql-devel-8.2.3-1mdv2007.1
libpq5-8.2.3-1mdv2007.1.i586.rpm
libpq5-devel-8.2.3-1mdv2007.1.i586.rpm
libecpg5-8.2.3-1mdv2007.1.i586.rpm
libecpg5-devel-8.2.3-1mdv2007.1.i586.rpm
And when I'm trying to install
postgresql-server-8.2.3-1mdv2007.1.i586.rpm I get:

Preparing...          ########################################### [100%]
