I think the problem appears to be the lack of build section in my meta.yaml file?

[msarahan]

Yes, in order to use the post-build versioning, you must have the build section in your meta.yaml file. We can fix that by adding the 'build' key if it doesn't exist.

As you've mentioned in #8, post-build versioning is deprecated. Post-build versioning makes it impossible to reason about the filename that will be output by a build, which in turn breaks other parts of conda-build, such as pre-rendering templates, and outputting built package filenames without actually doing a build. I could not come up with good reasons why versions can't be known before a build. I'm open to discussion if you have ideas. I think your versioning needs will be well-met with jinja2 templating, though, and I'm happy to answer questions you may have on that.
