@mayabrandi , I think that we may have problems here: ```bcbio.pipeline.config_utils``` is how the config loader is called in the new bcbio-nextgen, but in the old one, and this is the one that we have in production now, the import should be ```bcbio.pipeline.config_loader```. I'm afraid I have to ask you to make the last small but needed change. You can try-catch the import like this:

```
try:
    import bcbio.pipeline.config_utils as cl
except ImportError:
    import bcbio.pipeline.config_loader as cl
```

This way you avoid a import crash between bcbb and bcbio-nextgen.

Please make this last commit so I can merge.
