Can you either point me to the message, or post it again if the problem
is still unresolved?  Sorry that I missed those!

The problem is with the SelfLoader module. You can edit
lib/Term/ReadLine/readline.pm and comment out 2 lines:

    use SelfLoader;
and
    __DATA__

and things should work fine again.  I think SelfLoader is really just
cargo cult programming; I haven't seen any evidence that it actually
speeds up program startup time in a noticeable way.

You may not need feature.pm; it is implicitly required by the

    use 5.009005;

line in SelfLoader.pm.
