I've read through your postings, but there is not nearly enough information to debug your problem. The original post only shows expected results, not errors. I just tried installing on a RedHat Linux AS v3 system that has Oracle 9.2 to see if there were any difficulties.
First, did you install Oracle 9.2 correctly. You need more than Oracle client. There is no need to create a database, but you need more than a runtime software tree.
Second, are you on Unix or Linux? What version exactly?
Third, it would be a good idea to export a few environment variables:
export ORACLE_HOME=/usr/oracle (or whereever you put it)
export LD_ASSUME_KERNEL=2.4.1 (don't ask me why, but it can make a difference)
Fourth, install DBI-1.48 from CPAN. You are required to have one DBI installed before installing a DBD. It is done in the usual way, see the README.
Five, install DBD-Oracle-1.16 from CPAN. Before running "make test", you need to:
export ORACLE_USERID="scott/tiger"
Good Luck!
