Making a RPM installer

Hi,

Not sure if this the correct place to post this issue but hopefully
someone can help.

I am building a rpm for RHEL 5
    The rpm contains a compiled version for  postgresql-8.3.3 and tomcat
6 and java 1.6.

     When i try to install the rpm on blank test system i get the
following dependence issues

        libodbc.so is needed
        libodbcinst.so is needed


Postgresql has been compiled with the following line

    ./configure --without-readline --without-zlib

Any help would be greatly received.
