#58934: 'stack' port does not build solely from a MacPorts mirror

----------------------+--------------------
 I'm on a Macbook Pro running on an isolated network, using a mirror for
 MacPorts files.

 I'm trying to update `pandoc`, which pulls in `stack` as a dependency, and
 `stack` won't build because it's trying to get stuff directly from GitHub:

 {{{

 `main.log` attached.

 We have a limited mirror of GitHub (the limit is it only mirrors a
 whitelisted set of repos). Is there some way I can get a list of GitHub
 repos to mirror and point MacPorts at our mirror?
