A simpler way to do this might just be to re-run runInstaller from your Disk 1 staging area.

Then minimally pick 9.2.0.4 Client, then Administrator (Runtime did not provide pro*c libraries).

Choose Custom, and note that by default OCI - Oracle Call Interface -is not installed.

Installed OCI to get the appropriate .h files, and then the make for DBD-Oracle with 9.2.0.4 worked fine.
