I tried to follow your steps.
downloaded zip file and extracted DBD-Oracle-1.17.tar.gz and DBD-Oracle.ppd.
I put the ppd file in c:\Perl\install-folder\Perl and .gz in c:\Perl\install-folder\Perl\MSWin32-x86-multi-thread-5.8.
Then I extracted all the files from DBD-Oracle-1.17.tar.gz using winzip. and then ran "perl ioic" from this folder.
It then gave me this error 
C:\Perl\install-folder\Perl\MSWin32-x86-multi-thread-5.8>perl ioic

I have oracle client installed on the xp machine, though.
