Done by cc-ing BUGNUMBER-done <at> debbugs.gnu.org. Please be careful to not send all

I brought this to the help mailing list, and now I see it as a
particular bug in guix. When I change into a guix environment and try
to run a Python project that uses the WebKitGTK2 library, it cannot
find the specified shared library, even though it is in $LIBRARY_PATH.
As a result, the project crashes. This does not happen when I call guix
build. On a side note, guix build fails due to another error (possibly
related).

Thanks in advance for looking into this.
