Cant load steamvr xr runtime

I just installed simula via the install script on arch linux with steamvr 2.9.6
xrgears works fine however simula fails to load the steam xr runtime:

Error [GENERAL | xrEnumerateInstanceExtensionProperties | OpenXR-Loader] : RuntimeInterface::LoadRuntime skipping manifest file /home/user/.config/openxr/1/active_runtime.json, failed to load with message "libuuid.so.1: cannot open shared object file: No such file or directory"
Error [GENERAL | xrEnumerateInstanceExtensionProperties | OpenXR-Loader] : RuntimeInterface::LoadRuntimes - failed to load a runtime
Error [GENERAL | xrEnumerateInstanceExtensionProperties | OpenXR-Loader] : Failed to find default runtime with RuntimeInterface::LoadRuntime()
Error [GENERAL | xrEnumerateInstanceExtensionProperties | OpenXR-Loader] : Failed querying extension properties
Error [GENERAL | xrResultToString | OpenXR-Loader] : No active XrInstance handle.

libuuid.so.1 exists ofc in /usr/lib/ other consumers of openxr dlopen this file just fine. I gues this has something to do with the way simula uses a nixos runtime

Start by reproducing the install-script setup on Arch Linux with SteamVR 2.9.6, comparing Simula with the working xrgears case. Investigate the OpenXR runtime manifest at active_runtime.json and the reported libuuid.so.1 loading failure; done means Simula loads the SteamVR OpenXR runtime successfully.
