After installing Oracle instant client, if you have them in /usr/local/lib/instantclient_10_2, this is the command line i use :
./configure –with-instant-client=/usr/local/lib/instantclient_10_2 –with-oracle-includes=/usr/local/lib/instantclient_10_2/sdk/include –with-oracle-libraries=/usr/local/lib/instantclient_10_2 –with-oci-version=10G
Let me know ny email if you want the deb for ubuntu linux.
