It can't find oracle.mk so it dies. I'm also going to contact the DBD::Oracle module author, but just in case someone on these forums has already solved this, I'm also posting here. The output from the install was:
CPAN.pm: Going to build T/TI/TIMB/DBD-Oracle-1.16.tar.gz

Remember to actually READ the README file!
Especially if you have any problems.
Using Oracle in /usr/lib/oracle/xe/app/oracle/product/10.2.0/server

SQLPLUSRELEASE = "1002000100" (CHAR)
Oracle version 10.2.0.1 (10.2)
Unable to locate an oracle.mk, proc.mk or other suitable *.mk
file in your Oracle installation. (I looked in
/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/rdbms/lib/oracle.mk /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/rdbms/demo/oracle.mk /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/rdbms/demo/demo_rdbms.mk /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/otrace/demo/atmoci.mk /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/precomp/demo/proc/proc.mk /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/precomp/demo/proc/demo_proc.mk /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/proc/lib/proc.mk /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/proc16/lib/proc16.mk)
The oracle.mk (or demo_rdbms.mk) file is part of the Oracle
RDBMS product. The proc.mk (or demo_proc.mk) file is part of
the Oracle Pro*C product. You need to build DBD::Oracle on a
system which has one of these Oracle components installed.
(Other *.mk files such as the env_*.mk files will not work.)
In the unlikely event that a suitable *.mk file is installed
somewhere non-standard you can specify where it is using the -m option:
perl Makefile.PL -m /path/to/your.mk
See README.clients for more information and some alternatives.
at Makefile.PL line 922.
So
is there a different *.mk file that can be specified per the above?
