I'm not sure what the problem on your system is. Could you please try to
sync the pip versions?
Although you mentioned you installed avocado first. That should not
cause any problems, I usually do the same. The result is that with the
`make link` you're using the source code version even when runnin
`avocado` directly from any location and you use the system-wide version
after execution `make unlink`.
If the above does not help, try reinstalling/updating your system,
Fedora 20 is not officially supported (although as you can see it works
well).
Regards,
Lukáš
PS: CCing Cleber as he's more skilled in the plugins system.
