I think you actually want to be using a different guix environment 
command.

guix environment --pure --ad-hoc guile guile-readline

should get you what you want. The difference is that without --ad-hoc, 
what you're asking for is an environment with all the dependencies of 
guile and guile-readline. This is useful, for instance, if you want to 
work on those packages. In this case, guile is available because 
guile-readline depends on it, but nothing depends on guile-readline, so it 
is not in the environment.

With --ad-hoc, you specify the the packages you want in the environment 
explicitly.

See the manual [0] for more information and more advanced usage of 
environment.

This isn't the first time the --ad-hoc has caused confusion. I tend to use 
that option more often than not. There was previous discussion [1] about 
making environment more friendly to use interactively without breaking 
compatibility, but more work is still needed on that front.

Hope that helps,
