Unused variables aren't too much of a problem.
The parse error is due to the presence of this at line 2064 in dbdimp.ec:
(void)SvOK_off(sv);
This is a known defect - fixed by changing the line to read:
sv_setsv(sv, &PL_sv_undef);
Answering some later questions - no, Perl 5.8.1 isn't a dead loss,
though it is no longer recommended.
Personally, I don't use the system supplied Perl on any machine - but
then I'm not working in production environments. I'd be very leery of
installing extra modules into the system version of Perl, so I'd have
to mess around with a private Perl library directory and appropriate
environment variables or wrappers.
