Here it is!

"When creating the derivation" sounds like it's when the package is lowered
to a derivation, but from what I can see of ld-wrapper in (gnu packages
base) the actual substitution is done when the derivation is built. I
am curious how one would go about doing the substitution when the
package is lowered to a derivation, though. Anyway, for now I'm doing
the substitution at derivation-build-time.

Should I mention this somewhere?

Also, I should add that "guix lint" and indent-code.el both want changes
to gnu/packages/python.scm, but not due to changes I made. Should a
separate patch address those?

Let’s close it and Caleb or anyone is welcome to reopen it if there’s
interest.

Thanks,
