SpamAssassin without DCC is useless as you all know, upgrading to v3.2.2. made DCC not working giving setuid error on Util.pm of SpamAssassin.
What you will have to do solving the issue is installing Patch#4077 over Bug#5574.
Here is how to do this:
Go to your downloaded source code of SA and run these:
wget -k -O bug5574_patch4077.patch "http://issues.apache.org/SpamAssassin/attachment.cgi?id=4077&action=view" patch -p0 < bug5574_patch4077.patch
perl Makefile.PL
make && make install
