I am sorry for the <code> etc.
Yes, i can run perl without any problem. But all packages related to CPAN produce segmentation fault. Even after reinstalling perl-libwww-perl, cpan and perl itself it again produces segmentation fault. Still CPAN and most of the packages related to it with produces segmentation fault.
Thanks
For more information, I am using dnf updates and reinstall in fedora 22. Even locally i try to recompile perl-libwww-perl but http.t and ua-get no longer working. Even perl Makefile.PL produces segmentation fault. So this problem is centered only at CPAN.
