That just means it didn't need to rebuild it. With `--lib` (run in
your config directory) it should have placed a reference in
.ghc.environment.x86_64-linux-9.2.2 (or the file for your arch and ghc
version) pointing to that build.

(The `grep X11` is to exclude packages like `lens` that have their own
`….Extras` modules.)
