bootstraping sdn-ixp

[dkalog]

I am trying to fire-up the sdn-ixp according to the installation instructions of https://github.com/sdn-ixp/sdx meaning the https://docs.google.com/document/d/1wLF3RZEwMCRioyvaVl73kjXeNgqIaA3LfUlGsI2mkb4/edit . However when I try to start the pyretic SDX controller, I get the following error message :
mininet@mininet-vm:~/pyretic$ pyretic.py -v high pyretic.sdx.main
Must be a valid python module
e.g, full module name,
no .py suffix,
located on the system PYTHONPATH

However my PYTHONPATH is mininet@mininet-vm:~/pyretic$ echo $PYTHONPATH
/home/mininet/pyretic:/home/mininet/pyretic/pyretic/sdx:/home/mininet/mininet:/home/mininet/pox

Any hints ?

i seem to have gotten past here by removing the pyretic directory, cloning the one from www.github.com/frenetic-lang/pyretic, and then applying the checkout as mentioned in the document. But now I get this:
