spamassassin needs what version of perl

I have perl5.00503 on my system, an old SuSE 6.4. I just downloaded and built spamassassin 2.31 and seem to be missing a perl module it uses (Pod::Usage). I don't see anything that indicates what version of perl spamassassin requires. Does anybody know? While running the recommended tests I get the following error output: ~/Mail-SpamAssassin-2.31 > spamassassin -t nonspam.out Can't locate Pod/Usage.pm in @INC (@INC contains: /usr/lib/perl5/5.00503/i586-linux /usr/lib/perl5/5.00503 /usr/lib/perl5/site_perl/5.005/i586-linux /usr/lib/perl5/site_perl/5.005 .) at /usr/bin/spamassassin line 8. BEGIN failed--compilation aborted at /usr/bin/spamassassin line 8. Thanks, Jim
