At least for me, the problem shows up simply with vulkan-tools installed (or 
using "guix shell vulkan-tools") using a guix commit after the latest (1.3.280) 
vulkan updates. Simply running "vulkaninfo" results in the error:

ERROR at 
/tmp/guix-build-vulkan-tools-1.3.280.0.drv-0/source/vulkaninfo/./vulkaninfo.h:412:
 Failed to initialize: Vulkan loader is not installed, not found, or failed to 
load.

A bit of local testing just now suggests setting LD_LIBRARY_PATH to the 
vulkan-loader package's lib dir should be enough to resolve the error.
