[chef] Easy Install Error for Pisa

[Chris Spencer < >]

Hi,

I'm new to Chef, and I'm trying to automate the installation of the Python package "pisa". I was hoping to use the "easy_install_package" function, which I'm using like:

easy_install_package "pisa" do
    version "3.0.27"
end 

but this throws the error:

The problem seems to be that easy_install_package is running 'python -c "import pisa; print pisa.__path__"', which of course will throw an error, because the actual module imported is called "ho.pisa", not "pisa", even though the egg file is simply called "pisa". How can modify easy_install_package to use the correct package name?
