strange, i did not get the email from rt, which is why i didn't have a
look at them. :-(

sorry, but check_upstream_availability is done in START event from
app::cpan2pkg::worker class, and thus for each new module. indeed,
there's a new worker session created for each module to be investigated.

your error comes from this in the output:

    * 22:16:46 Running: cpanp /prereqs show Carp::REPL

    [ERROR] No such plugin command


==> you need to install
perl-CPANPLUS-Shell-Default-Plugins-Prereqs-0.100.0-1.mga3.noarch.rpm
