I'm working on packaging goldendict, a dictionary reader, along with
many free dictionaries in various languages. This essentially requires
"optional dependencies", a concept alien to Guix's functional model.
However some by default goldendict checks directories such as
/usr/share/stardict/dicfor dictionaries, but Guix has 2 other locations
dictionaries may be found; /run/current-system/profile/share/..., and
$GUIX_PROFILE/share/...
A couple packages like ibus and aspell solve this using
'native-search-paths' which seems to require the program to have an
environment variable it checks for search paths, which goldendict
doesn't. There isn't much documentation on native-search-paths so I
don't know what it actually does.
libxt has a patch that hard codes the rule to check
/run/current-system/profile, and if GUIX_PROFILE exists, check that,
otherwise if HOME exists check $HOME/.guix-profile/...
That's the only solution I can see working unless anyone has a better
suggestion, I'd like to ask for some help writing the patch though since
I've never written any C/C++ before, I was stuck figuring out how to
define a string :(.

I think it can be done by making a copy of this code block and wrapping
it in the above logic:
https://github.com/goldendict/goldendict/blob/master/config.cc#L335
It would be good to keep the original /usr/share search paths so that
goldendict will interoperate if guix is installed on a foreign distro.
