	    If sqlplus failed due to a linker/symbol/relocation/library error or similar problem
	    then it's likely that you've not configured your environment correctly.
	    Specifically, your DYLD_LIBRARY_PATH environment variable
	    set to include the directory containing the Oracle libraries.
	    
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.

Oracle version 8.0.0.0 (8.0)
DBD::Oracle no longer supports Oracle client versions before 9.2 
 Try a version before 1.25 for 9 and 1.18 for 8! at Makefile.pl line 271.
