bug#65688: [PATCH 2/2] gnu: Add r-trackviewer.

[Ricardo Wurmus]

Thanks for the patch!

This one needed a little more work.  The “esbuild” in the native inputs
was added by the importer because the package includes minified
JavaScript files.

Luckily it’s just one file and we can replace it easily.  I’ve made the
necessary changes and pushed it with commit
8c0c94bf9f70a9252cd6f4261d2bce6bdba2bd0b to the “master” branch.
