Gosh, I am embarassed. The compiled files are indeed in the path Guile
was helpfully trying to point me at:

#+BEGIN_EXAMPLE
  $ ls -a 
/gnu/store/cd6rjv3qhhghr59wpq4fksfr84d5dsdf-guix-module-union/lib/guile/2.2/site-ccache/gcrypt/
  .  ..  base16.go  base64.go  common.go  hash.go  hmac.go  package-config.go  
pk-crypto.go  random.go  utils.go
#+END_EXAMPLE

So I went back and took Ricardo's advice and looked at the time's involved:

#+BEGIN_EXAMPLE
  $ stat 
/gnu/store/cd6rjv3qhhghr59wpq4fksfr84d5dsdf-guix-module-union/share/guile/site/2.2/gcrypt/hash.scm

It looks like the scheme file is fractions of a second newer than the
compiled file. So, pulling on this thread:

1. This looks like this has been an issue since I installed Guix. Did I
   do something wrong?
2. I feel like, regardless of the root-cause, some Guix command should
   be able to correct this issue for me, without necessarily having to
   know what went wrong or why.

Thank you all! And thoughts?
