Trying to fix exim from woody upgrade

["Bryan K. Walton" <walton@berbee.com>]

I am running the latest version of woody (including the brand new version of libc6 : 2.1.94-3).

I am also running the latest version of exim (3.16-3.1).  Ever since upgrading to this version of exim, I can't send any mail.  When I try, this is what I get: 

2000-09-30 14:42:10 13fSWQ-0001GF-00 Failed to create spool file
/var/spool/exim/input//13fSWQ-0001GF-00-D: Permission denied
2000-09-30 14:42:10 13fSWQ-0001GF-00 Failed to create spool file
/var/spool/exim/input//13fSWQ-0001GF-00-D: Permission denied
2000-09-30 14:42:10 13fSWQ-0001GF-00 Failed to create spool file
/var/spool/exim/input//13fSWQ-0001GF-00-D: Permission denied

I can't downgrade to the stable version of exim because I get a message saying that it conflicts with the new version of libc6.  Is this simply a permissions issue in my mail spool at the error sugggests?  I haven't altered the permissions manually (don't know if apt-get did it for me when upgrading exim).

Here is the permissions on my /var/spool/exim directory:
drwxr-x---    5 mail     mail         4096 Sep 30 12:41 exim

and my input directory:
drwxr-x---    2 mail     mail         4096 Sep 30 12:42 input

Thanks,
