in reply to migrate cpan from AIX to Red Hat
Avoid using the system Perl if you can. Have your users/applications use a local installation of Perl. This prevents Perl module conflicts with what RHEL is expecting. It also has the benefit of when you upgrade to the new version of RHEL (or migrate to another machine), you can just tar ball the Perl directory and extract.
