There may be a problem upgrading the CPAN module in Mac OS X El Capitan and Sierra releases. Solution: http://www.perlmonks.org/?node_id=1144321

Aperently in these OSX versions, applications can not whrite on /usr with temporary sudoer rights.

Start CPAN interactive shell

$ cpan

Change CPAN configuration

cpan> o conf makepl_arg "INSTALLBIN=/usr/local/bin INSTALLSCRIPT=/usr/local/bin"

Save changes

cpan> o conf commit

Quit CPAN interactive shell

cpan> quit
