After a *very* quick look at CPAN.pm, it looks like your
CPAN/Config.pm is incomplete, so it tries to rebuild it, but trips up
because it is not expecting the Config.pm file to not be writable when
the CPAN/ directory is writable.

This is IMO a CPAN bug.

You can find out what's missing by:

perl -MCPAN::Config -MCPAN -wle'print for CPAN::Config->missing_config_data'

As a workaround, you may just want to copy it to ~/.cpan/CPAN/Config.pm and use

perl -Mlib=$HOME/.cpan -MCPAN -eshell
