That's not how any of this works.  Even if Lagrange were to mystically
pick up packages from your environment, which more likely than not it
doesn't, you would still have to include it in said environment for it
to make a difference.

I suggest trying a variant of lagrange that has harfbuzz to verify that
it indeed does make a difference.  You can construct one by editing
Guix source or by using the following with the right (use-modules ...)
clause on top:

(package
  (inherit lagrange)
  (inputs 
   `(("harfbuzz" ,harfbuzz)
     ,@(package-inputs lagrange))))

Alternatively, someone else might try given the file you've provided,
just putting this out there if you want to experiment on your own :)

Regards,
Liliana
