"uninitialized value" and other errors with SA 3.0.2

[Brian Kendig]

I'm getting errors when I try to use SpamAssassin 3.0.2 (and the same 
errors with 3.0.1), on Mac OS X 10.3.7.  Specifically, when I call it 
from a command line with no arguments (same as if I give it "-t < 
sample-spam.txt"):

$ spamassassin
Global symbol "$re_strict" requires explicit package name at 
///Library/Perl/5.8.1/Mail/SpamAssassin/PerMsgStatus.pm line 1224.
Global symbol "$re_loose" requires explicit package name at 
///Library/Perl/5.8.1/Mail/SpamAssassin/PerMsgStatus.pm line 1224.
Global symbol "$re_strict" requires explicit package name at 
///Library/Perl/5.8.1/Mail/SpamAssassin/PerMsgStatus.pm line 1229.
Global symbol "$re_loose" requires explicit package name at 
///Library/Perl/5.8.1/Mail/SpamAssassin/PerMsgStatus.pm line 1229.

BEGIN failed--compilation aborted at 
///Library/Perl/5.8.1/Mail/SpamAssassin.pm line 62.
Compilation failed in require at /usr/bin/spamassassin line 69.

And when I call it from my Exim 4.43 mail server through SA-Exim, these 
errors appear in my mail.log:

spamd[16237]: connection from localhost [127.0.0.1] at port 54762
spamd[16245]: processing message 
<[EMAIL PROTECTED]> for exim:-2.

spamd[16245]: clean message (0.0/5.0) for exim:-2 in 4.4 seconds, 1058 
bytes.

SpamAssassin 2.64 works just fine.
Is this a bug in SpamAssassin 3.0.2, or am I doing something wrong on 
my end?
