MailScanner, CentOS 5 and perl-IO & perl-File-Temp

[Julian Field]

In a recent version of MailScanner, do a "./install.sh --help".
After a few seconds it will print this:

Usage: ./install.sh [OPTION]... [VAR=VALUE]...

   -h, --help            display this help and exit
   nodeps                ignore dependencies when installing MailScanner
   ignore-perl           ignore perl versions check
   fast                  do not wait for long during installation
   reinstall        force uninstallation of Perl modules before install
   nomodules             do not install required Perl modules

Note the "reinstall" option.
What you want to do is this.
     ./install.sh reinstall
Then it will uninstall the Perl modules, at which point you "Ctrl-Z" it, 
run your "yum update" and let your system happily upgrade. Then "fg" to 
bring the install.sh script back to the foreground and let it complete 
the install.

Net result, a neatly upgraded system without having to fart around 
manually uninstalling Perl module RPMs.

To give you an example, this is what you will see when you run 
"./install.sh reinstall" after the usual introductory output:

===START===
I think your system will build architecture-dependent modules for x86_64

Deleting all the old versions of your Perl modules,
I will re-install them in a minute.

Removing perl-Net-CIDR
Removing perl-IO-stringy
Removing perl-MIME-Base64
Removing perl-TimeDate
Removing perl-Pod-Escapes
Removing perl-Pod-Simple
Removing perl-Test-Simple
Removing perl-Test-Pod
Removing perl-MailTools
Removing perl-IO
Removing perl-File-Temp
Removing perl-HTML-Tagset
Removing perl-HTML-Parser
Removing perl-Convert-BinHex
Removing perl-MIME-tools
Removing perl-Convert-TNEF
Removing perl-Compress-Zlib
Removing perl-Archive-Zip
Removing perl-DBI
Removing perl-DBD-SQLite
Removing perl-Getopt-Long
Removing perl-Time-HiRes
Removing perl-Math-BigInt
Removing perl-Math-BigRat
Removing perl-bignum
Removing perl-Net-IP
Removing perl-Sys-Hostname-Long
Removing perl-Sys-Syslog
Removing perl-Digest-SHA1
Removing perl-Net-DNS
Removing perl-OLE-Storage_Lite

If you want to upgrade your version of Perl, then now is a good time
to press Ctrl-Z, upgrade everything, and then continue this script
by running the "fg" command.
===END===

Hopefully that's all clear enough that you can see what you need to do.

Jules.
