OK, the problem is that the kernel that is being loaded is the Python
one.

Which version of IPython are you using? I have 2.1.0 here.

    $ ipython --version
    2.1.0

The way that IPython sets up the language kernel is through profile
configurations. Perhaps deleting the profile directory and rebuilding it
might help? 

    rm -Rf `ipython locate profile perl`           # delete an existing profile

Then try running

    ./bin/iperl notebook

again. That should copy the profile into the directory. If that doesn't
work, we can try doing what the iperl script does manually:

    # from the p5-Devel-IPerl directory
    rm -Rf `ipython locate profile perl`             # delete an existing 
profile (start off with a clean slate)
    ipython profile create perl                      # create a Perl profile
    cp -vR profile/* `ipython locate profile perl`/  # copy the config into the 
profile directory
    export PERL5LIB=`pwd`/lib:$PERL5LIB              # so that Devel::IPerl is 
in @INC
    ipython console --debug --profile perl           # start IPython with Perl 
kernel config (and debugging enabled)

Let me know if that works.
