Wow, my first contact with ~guix import~, this tool is a gem!
Seems to work perfectly.

I've enabled the tests but it fails there:

	Can't locate IO/All.pm in @INC (you may need to install the IO::All module) (@INC contains:
/gnu/store/w96mglkim3p2ryb72flhzlsyv618fhk2-perl-5.26.1/lib/perl5/site_perl/5.26.1/x86_64-linux-thread-multi ... at /tmp/guix-build-fortune-mod-2.4.1.drv-0/fortune-mod-fortune-mod-2.4.1/fortune-mod/tests/t/check-cookies.t line 6.

Is IO::All really missing from Guix?
