MNT: Re-render the feedstock (paused due to conda-build <2)

[conda-forge-admin]

Hi! This is the friendly conda-forge-admin automated user.

I've re-rendered this feedstock with the latest version of conda-smithy (1.3.1) and noticed some changes.
If the changes look good, then please go ahead and merge this PR.
If you have any questions about the changes though, please feel free to ping the 'conda-forge/core' team (using the @ notation in a comment).

Remember, for any changes to the recipe you would normally need to increment the version or the build number of the package.
Since this is an infrastructural change, we don't actually need/want a new version to be uploaded to anaconda.org/conda-forge, so the version and build/number are left unchanged and the CI has been skipped.

Thanks!

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

The reason this has failed is that we are using a conda-build that has a broken conda inspect:

+ conda inspect linkages -p /opt/conda/envs/_test netcdf4
Traceback (most recent call last):
  File "/opt/conda/bin/conda-inspect", line 5, in <module>
    sys.exit(main())
  File "/opt/conda/lib/python3.5/site-packages/conda_build/main_inspect.py", line 172, in main
    default=config.prefix_length,
AttributeError: 'Config' object has no attribute 'prefix_length'
TESTS FAILED: netcdf4-1.2.4-np110py27_2

@jakirkham - I have been out of the loop for a while - is there a link you can xref me on please? I'd like to start that ball rolling so that we can update conda-build (discussion on that to take place at your xref if that is ok 😄 ).

[jakirkham]

Not really one point of discussion, but maybe issue ( conda-forge/conda-forge.github.io#171 ) would be a good place to handle the remaining pieces.

Done in #21
