"Updating nibabel-target": that's not the same part as that "mypy" 
target. Note that such an eggs attribute is only valid for that one part.

So "[nibabel-target]" also should have an eggs attribute with numpy in it.

Perhaps handier: add an "eggs" attribute to [buildout] with nibabel and 
numpy in it and use that:

[buildout]
....
eggs =
     nibabel
     numpy

[mypy]
...
eggs = ${buildout:eggs}
...

[nibabel]
...
eggs = ${buildout:eggs}
...



DOes that work?
