The problem here is that `Wand-config` is just a plain dumb shell script. And it does invoke `pkg-config`. As you might imagine, whenever you run a shell script and it, in turn, runs a command, what happens is exactly the same as when you run run that command yourself: it is being looked up in $PATH, etc.
You installed imagemagick, and its tools (including `Wand-config`) were added to your $PATH. It needed pkg-config during the build process, so pkg-config was in `buildInputs` and as a result, it _was_ added to $PATH during the build. But now it is not in your $PATH, that’s why `Wand-config` fails. Long story short, that is an issue with imagemagick packaging. All the references to `pkg-config` should have been replaced with absolute paths somewhere during the build process. If you feel like fixing this, something like this <https://github.com/NixOS/nixpkgs/blob/d4681bf62672083f92545e02e00b8cf040247e8d/pkgs/build-support/dotnetbuildhelpers/default.nix#L15> should be done. In the `postPatch` phase, probably.
