mach: Good way to build the rpm from CPAN perl modules

Mach is very interesting way to build the rpm of CPAN perl modules. Very easy to install, create the build environment.

I used link How to Build RPM Packages in A Chroot Environment using mach
This link has given reasonably good procedure to create the rpms.

Make sure - you have packages like gcc, make installed. Also you have access to latest spec file, access to download the latest source tars/gzs from CPAN.
