I told you already > that I have spamassassin running with these packages with no problems: Although I have the 32-bit packages which could be slightly different, no?

It seems like it shouldn't be hard to grep for who the culprit is, but what do I know - doing this didn't turn up anything I could too easily decypher: cd /usr/lib/perl5 grep -rin 'af_inet6' * I only got 40 lines of output from that so I could post them if needed. Grepping exactly for "sub af_inet6" gives me only one result: 5.8.8/i386-linux-thread-multi/bits/socket.ph:66: eval 'sub AF_INET6 () { &PF_INET6;}' unless defined(&AF_INET6); Are there modules that are placed somewhere other than /usr/lib/perl5 that could have the offending code? Or is this a fruitless way to track down the problem?
