 ## Reproducing the Error
 
+UPDATE: The problem is because this example relies on a library that uses CGO
+to wrap the Proj library.
+As the library was not installed locally, the export files weren't generated
+by the GC compiler.
+I've since modified the Dockerfile to install golangci-lint v1.50.1 and ran
+golangci-lint within the container itself and the error no longer appears.

 $ golangci-lint --version
