+        $cargoBuildLog is either undefined or does not point to a valid file location!
+        By default `buildPackage` will capture cargo's output and use it to determine which binaries
+        should be installed (instead of just guessing based on what is present in cargo's target directory).
+        If you are overriding the derivation with a custom build step, you have two options:
+        1. override `installPhaseCommand` with the appropriate installation steps
+        2. ensure that cargo's build log is captured in a file and point $cargoBuildLog at it
+        At a minimum, the latter option can be achieved with running:
+            cargoBuildLog=$(mktemp cargoBuildLogXXXX.json)
+            cargo build --release --message-format json-render-diagnostics >"$cargoBuildLog"
+      ''}
