DBD::Oracle on AIX 5.1

I installed DBD::Oracle on an IBM AIX 5.1 box, and for once I have some good news. Anyone who has ever tried this will know of some of the troubles I speak of. When dealing with DBI and any DBD on a AIX box, you either must either be lucky enough to have the same compiler installed that built the version of Perl that comes with the box (I have never seen this happen); or you have to spend a great deal of time downloading and installing your own GCC and the building your own version of Perl.
