Problem installing MARC::Record 2.0.0 under perl 5.8.0

I am in the process of rebuilding my web site after a phishing site break-in
(yikes!). The site is fine now, and secure, but for some reason I can't get
MARC::Record-2.0.0 to install. I get an error message saying that perl 5.8.2
is required, but that I only have perl 5.8.0. (And indeed I do have perl
5.8.0) But I'm pretty sure this version of MARC::Record *did* install under
perl 5.8.0 that last time I tried.
 
I cheated by changing line 2 in the Makefile.PL file to read "require
perl-5.8.0" instead of "5.8.2". It installed, but it only passed about 20%
of the tests during make test. Am I asking for trouble here? Will it work,
or should I try installing an earlier version? (If so, which earlier
version, and where should I get it?) Also, I saw a patch somewhere that you
could use if you're installing into systems that use Perl 5.00xxx or earlier
(or something to that effect).

Any thoughts from anyone on this?
 
Many thanks!
