Reconfigure command in "perl -MCPAN -e shell"
 

I made a bit of an error.

I started
~>perl -MCPAN -e shell

without installing make.

Now I DID install make perl keeps complaining it cannot run "make test".

How do I force the CPAN script to reconfigure itself?

Try
reload CPAN
after you get in. Not sure if that's it, but it's the best looking option in help. Or try www.perlmonks.org
The other obvious optin is uninstall, reinstall CPAN or even Perl, but that's a bit drastic.... try the monks.
