CPAN Error: Undefined subroutine &IO::Uncompress::Base::readonly called at /usr/lib/perl5/site_perl/5.8.8/IO/Uncompress/Base.pm Looks like CentOS update installs an older version of the Scalar::Util so that Perl could not load the module. Download the Scalar::Util module and manually install it:
wget http : //search.cpan.org/CPAN/authors/id/P/PE/PEVANS/Scalar-List-Utils-1.35.tar.gz
tar xvzf Scalar - List - Utils - * . tar . gz
cd Scalar - List - Utils - *
perl Makefile . PL
gmake
gmake test
gmake install
To test: perl -MCPAN -e ‘shell’ For more information, visit the CPAN Util.pm page. Original Post: http://www.perlmonks.org/?displaytype=print;node_id=965635;replies=1

I had to patch the distribution by adding the following variable into the code: $Config::Auto::Untaint = 1; Here is the fix on AWS Linux: vim /usr/local/share/perl5/CGI/Application/Plugin/ConfigAuto.pm 141 sub cfg { 142 my $self = shift; 143 144 if (!$self->{__CFG}) { 145 require Config::Auto; 146 $Config::Auto::Untaint = 1; (ADD THIS NEW LINE HERE)

Perl to the Rescue! This perl script cleans just one type of infection as an example. Vary the script to search for and clean other combinations and patterns. Also, the script is deliberately written long-hand and verbose, and could be significantly more compact and efficient. It was done this way for ease of use and […]

This solution is hyper-simplistic, and does not deal with decimals or real numbers (those with either a – or a + in front of them)…
if ( $ value = ~ / ^ \ d + $ / ) {
## $value is an integer
} else {
## $value is NOT an integer
}

You could try using -- skip - broken to work around the problem
You could try running : rpm - Va -- nofiles -- nodigest
