This bug still exists if one installs Scribus through Guix in a foreign system distribution. Even though I still have both LD_LIBRARY_PATH and PYTHONPATH variables unset and I don't have Python installed through Guix.
However, today I decided to test with: $ guix environment --ad-hoc scribus python@2.7 bash -- bash And after the environment was set, I did: $ echo $PATH /gnu/store/1cvfwh7qj6c2vgkbancql9phrm64dh9d-profile/bin:/home/adfeno/.guix-profile/bin:/home/adfeno/.guix-profile/sbin:/home/adfeno/.guix-profile/bin:/home/adfeno/.guix-profile/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games $ echo $PYTHONPATH /gnu/store/1cvfwh7qj6c2vgkbancql9phrm64dh9d-profile/lib/python2.7/site-packages $ echo $LD_LIBRARY_PATH $ scribus And then Scribus lauched (although with errors about missing images which I'll ignore for this bug). One way out of this bug would be to investigate/fix the hardcoded paths that Scribus might have according to what ludo said ([[http://lists.gnu.org/archive/html/bug-guix/2016-11/msg00077.html]]). Other possibility is to test moving the Python dependency from the package's inputs to native-inputs or propagated-inputs. But this is just an idea from a non-developer (me), so I don't know if this is really the cause of the problem. -- - [[https://libreplanet.org/wiki/User:Adfeno]] - Palestrante e consultor sobre /software/ livre (não confundir com gratis). - "WhatsApp"?
