Figured this one out: The Makefile.PL for DBD::Oracle looks for makefiles in your oracle home directory. If it finds one, it scans the makefile for compiler options used to build Oracle applications.
In my case it found demo.mk which includes the option -locci. What is interesting is that the makefiles are not present in the instant client zip archives that Oracle makes available. So it appears that libocci will get included or not depending on what kind of client distribution you have. Is anyone having problems using DBD::Oracle in a mod_perl environment when libocci is _not_ linked in? I'm using perl 5.12.2 without threading enabled.
