Hi Couten,
This looks pretty much like an issue with virtualenv (setuptools) on
Ubuntu 10.10. I can reproduce the same AssertionError on my Ubuntu
10.10 VMWare guest machine when I use virtualenv --setuptools to
initialize the virtualenv.
Since zc.buildout in some degree takes care of isolating the TyphoonAE
dependencies from the installed system packages, you could try to
install it without virtualenv. This solved the issue on my debug box.
Just to make sure, have you installed all packages listed here
http://code.google.com/p/typhoonae/wiki/GettingStarted#Other_requirements
?
Hopefully, this works for you. Don't hesitate to post any further
question or issue with TyphoonAE.
Thanks!
Tobias
