This is where you're running into problems. The clangd binary is 
actually installed into the "extra" output of the package. That's 
what the move procedure is doing in the snippet you quoted.

Since clangd is in the "extra" output, you should be able to 
install it using `guix install clang:extra`. I tried it out with 
`guix environment --ad-hoc clang@12:extra` and clangd was included 
in my PATH.

 $ guix environment --ad-hoc clang@12:extra -- which clangd
 /gnu/store/y1mnviajs1qniw0v497z66r5jr1zla9s-profile/bin/clangd

I hope that helps!
