STEPS TO REPRODUCE 1. Launch Poedit 2. Open the attached PO file (guix-website-es.po) EXPECTED RESULT ☑ Poedit displays the catalog correctly UNEXPECTED RESULT ☒ The catalog is not displayed. Instead you see an error: Poedit Error: Unhandled exception occurred: Cannot execute program: msgfmt -o /dev/null -c "/path/to/guix-website-es.po" WORKAROUND Start Poedit in a guix shell that adds gettext: guix shell poedit gettext poedit Then, you can open the PO files normally. So it seems the package definition for Poedit is missing gettext as a run-time dependency (?).
