Use a different construction here, to avoid unintentionally breaking the match with versionsuffix and dep:

```python
name = 'Mothur'
version = '1.30.2'

biodeps = 'biodeps'
biodeps_ver = '1.6'
versionsuffix = '-%s-%s' % (biodeps, biodeps_ver)

dependencies = [
    (biodeps, biodeps_ver),
    ('gzip', '1.5'),
]
```
