Using Oracle in C:\Program Files\Perforce
I'm having trouble finding your Oracle version number... trying harder

WARNING: I could not determine Oracle client version so I'll just
default to version 8.0.0.0. Some features of DBD::Oracle may not work.
Oracle version based logic in Makefile.PL may produce erroneous results.
You can use "perl Makefile.PL -V X.Y.Z" to specify a your client version.
