Respectful obeisances, My Perl installation got updated to 5.28.1 by my OS (openSUSE) and ever since then some of my scripts complain about missing some of my modules and cpan interactive shell quits with complaints about lock files and segmentation faults. I can usually install missing modules using cpanminus and proceed doing whatever I was doing but I still need to fix cpan. As of now, I get this (edit: corrected misspelled command in original message): 
stan@linux-pwfe:~> sudo perl -d -MCPAN -e shell
[sudo] password for root: 

Loading DB routines from perl5db.pl version 1.53

Enter h or 'h h' for help, or 'man perldebug' for more help.

Cpan itself responds to "sudo cpan -h" and "sudo cpan -v" and it even updated cpan itself via "sudo cpan -i CPAN". It can't find and install missing "CAN.pm" this way, though. Edit - another example: 
stan@linux-pwfe:~> sudo cpan
[sudo] password for root: 
Loading internal logger. Log::Log4perl recommended for better logging

There seems to be running another CPAN process (pid 8012).  Contacting

Other job not responding. Shall I overwrite the lockfile '/root/.cpan/
+.lock'? (Y/n) [y] y
