Check your $HOME path. Your two entries in the /etc/ld.so.conf file should probably look like:
I assumed your user name is jkite.
You could put the script commands above in your .bashrc or profile files.
One problem I see with this is that the openh323 software is installed for use by a user, but you are setting up library paths for the system. You may want to install the software as root in /usr/local or /opt instead of your home directory. You could also try installing the libraries in a currently accessed library directory such as /usr/local/lib and rerun ldconfig
