chat/emojisource.go:15:2: unrecognized import path "camlistore.org": https fetch: Get "https://camlistore.org/?go-get=1": dial tcp 104.197.157.20:443: i/o timeout
```
And `camlistore.org` is really unreachable. I have found the following two hints but after some patching it still does not build for me:
- https://github.com/perkeep/perkeep/commit/d6a0b05df0f1b1bd7ff0a3fc16a21561d84854d2
- https://pkg.go.dev/camlistore.org

Start in chat/emojisource.go, where the camlistore.org import is reported, and reproduce the failure with the provided go build command. Review the linked Perkeep commit and the camlistore.org package documentation to understand the dependency path. Done means the production build no longer depends on the unreachable camlistore.org endpoint and completes successfully.
