Hi Tobias,

thanks for the tip. Unfortunately the command you sent me is not
enough. I still get this error with `guix shell guix`:

```
[roman@thinkpad guix]$ guix shell guix -- ./pre-inst-env guix lint gdal

```

However, after adding guile-lib to my home profile, it seems to work!

Thanks, Roman.
