How to resolve this. Installed perl version is 5.10 and Linux version is Red Hat Enterprise Linux Server release 6.7 (Santiago)

Answer 1

Check required packages if they are 64-bit; i686=32-bit, x86_64=64-bit. Though I prefer installing latest perlbrew, not system perl, and then necessary modules through cpan. They may be newer than redhat perl ones.
