That script is a 0.11 series startup script, while you mention you are
running 0.10.  It seems you've somehow mixed up the installation of
the 0.10 and the 0.11 versions of IPython...  It's possible you have
in your $path a 0.11 startup ipcluster script, but the version of the
IPython package in $pythonpath is the 0.10 version...

I'd suggest cleaning up the combination and reinstalling, somehow you
have a weird hybrid...
