Yes, because you have bcbio-nextgen installed. The import will not work with bcbb:

[bcbb config_loader](https://github.com/SciLifeLab/bcbb/blob/master/nextgen/bcbio/pipeline/config_loader.py)
[bcbio-nextgen config_utils](https://github.com/SciLifeLab/bcbio-nextgen/blob/master/bcbio/pipeline/config_utils.py)

And we don't have bcbio-nextgen installed in production already.
