Oh, great, I didn't know about it, thanks! It will reduce the workaround. However, just using this package cannot solve the problem: 'sdl-config' points directly to "/gnu/store/…-sdl-1.2.15", so you need to modify a package anyway to make it find "/gnu/store/…-sdl-union-1.2.15/include/SDL" (that's why 'guile-sdl' specifies "--with-sdl-prefix="). -- Alex
