This means that something is changing your "view" of Guix. You aren't building the same things that the rest of us are building. Are you using any channels? Or maybe custom packages via GUIX_PACKAGE_PATH? Or anything else we should know about? Can you send the file '/gnu/store/b1vs7n6dvmsrk9510q8hqjnq6m9mvrm3-webkitgtk-2.32.0.drv' as an attachment? In the meantime I am testing the build with a single core.
