Hi all, This is an interesting thread: http://lists.centos.org/pipermail/centos/2014-April/141871.html about the problems you can find building perl modules for CentOS releases (new or old). I agree with John R. Pierce: cpan is very very bad tool ( in fact, I hate it) to build perl modules for CentOS systems, breaks all other perl modules. I need to use several perl modules in several servers in my dept. and after some tests, I migrate to FreeBSD due to easy install perl modules with poudriere suite. But, anyone knows if it is possible to build a confident devel environment under CentOS with some tool to build rpm's perl modules without breaking anything in CentOS systems?? Maybe, it is a good idea to create a CentOS Perl SIG :)) Thanks.
