Try to get tests passing in koji again.

> sys.version_info returns a tuple, so you can easily compare it directly: sys.version_info < (2, 6)

You know, I thought so too.  And I tried it, but it didn't work.

Trying again, perhaps only `<=` doesn't work... which makes sense since they're not really *equal*.

```python
>>> sys.version_info
sys.version_info(major=2, minor=7, micro=5, releaselevel='final', serial=0)
>>> sys.version_info <= (2, 7)
False
```
