Fixes #45

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

I wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found some lint.

Here's what I've got...

For recipe/meta.yaml:

• This recipe is using a compiler, which now requires adding a build dependence on {{ stdlib("c") }} as well. Note that this rule applies to each output of the recipe using a compiler. For further details, please see META: {{ stdlib("c") }} migration conda-forge.github.io#2102.

@conda-forge-admin, please rerender

@tegarriott the official website still refers to 3.4.0 as latest release, do you have any reference for the 3.4.1 release?

As discussed here ( #45 (comment) ), the plan is to backport a patch for the unreleased fix identified

Marking as draft for now to avoid confusion
