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.
