conda-forge build?

[ryan-salo]

I started the process to create a conda-forge version of this repo: https://github.com/ryan-salo/staged-recipes/tree/esa-snap.

However, I'm hitting an error with fonts not found during the update command and it enters into a never ending loop. Any tips on how to satisfy that dependency? I tried adding some env vars and fonts packages, but that didn't work. I also moved the post-link.sh content to build.sh, I wasn't able to see the error until I did that.
