Nov 03 2007 Update - Amavisd again failed to start after an update same error again. This resolved the problem.

I just did an yum update to Fedora 7 and rebooted seems that amavisd wasn't starting the complaint was about Compress::Zlib not loading.

Long story short when I ran perl -e 'use Compress::Zlib' to test it could load It threw up an error message as shown following

is only avaliable with the XS version at /usr/lib/perl5/site_perl/5.8.8/Compress/Zlib.pm line 9
Line 9 is this "use Scalar::Util qw(dualvar);" line

I tried to do an update using CPAN with the perl shell but an error kept occuring about gzopen not loading

A quick Google found a solution - download and manually install Scalar-List-Utils

wget http://search.cpan.org/CPAN/authors/id/G/GB/GBARR/Scalar-List-Utils-1.19.tar.gz

tar xzvf Scalar-List-Utils-1.19.tar.gz
cd Scalar-List-Utils-1.19
perl Makfile.PL
make test install

I got this info from a posting by this guy...
