Ok, the log shows nosetests coming from your global environment and thus all
subsequent invocations/import look ups happen there, i guess.  You need to make

sidenote: tox generally prints the cmdline invocations it does so you
should be able to re-produce things on the command line and 
poke around to discover whats going on.
