You need -L to follow location hints, however, that still has the same issue as mentioned in the changelog:

curl -L -O http://xrl.us/cpanm

                                 Dload  Upload   Total   Spent    Left  Speed

curl: (60) Peer certificate cannot be authenticated with known CA certificates
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

So you really need:

   curl -L -k -O http://xrl.us/cpanm

You'll also need that -k for use with the basic command line usage. People can probably work this out for themself,

    curl -L http://cpanmin.us | xxd
