More info

There appear to be two distinct problems: the "no buildable Go source files" warning re github.com/jeffjen/datefmt; and the "undefined: SassNumber" errors re github.com/wellington/go-libsass.

Before I added main: ./cmd/gojekyll to .goreleaser.yml, the commands above did create a release. The gojekyll in the release zip wasn't executable, though, since the config didn't refer to a main package. The build probably was skipping all the compilation, which is why it didn't run into the errors above. This does demonstrate that the upload part is (was) working.
