What are the contents of the above file now? Still (value #f)? Can you remove it, apply the patch below, and run: echo info /nix/store/i35q1vm2sl27sjhs7mx8n2m05056ya9x-subversion-1.7.8.tar.bz2 | \ sudo ./pre-inst-env guix substitute-binary --query (This is how the daemon invokes the substituter.) BTW, I assume that ‘make check’ passes, right? Thanks, Ludo’.
