Currently, the substituter fails for me. For instance, guix build pari-gp -n yields the following message: download-using-manifests.pl: error: executing `/usr/local/guix-git/libexec/nix/substituters/download-using-manifests.pl': No such file or directory guix build: error: build failed: substituter `download-using-manifests.pl' died unexpectedly
In fact, the directory /usr/local/guix-git/libexec/nix/ does not exist (any more?). There is /usr/local/guix-git/libexec/guix/, which does not contain the perl script. The culprit seems to be nix/libstore/globals.cc; or the script would have to be installed. Andreas
