Patching Snort 2.4.2 with ClamAV Errors

[Bill Warren <bwarren () optivel com>]

I just downloaded the latest everything and I am getting stuck.  Any
ideas?  I am running Debian Sarge with all the updates.

tar -zxvf snort-2.4.2.tar.gz
cp snort-2.4.2-clamonly.diff snort-2.4.2
cd snort-2.4.2
patch -p 1 < snort-2.4.2-clamonly.diff
