True, but it would be better than nothing - as long as it is not packaged for distributions, the code will most probably run on the machine where it has been compiled.

Well, if it solves the problem, it is worth the time!

The same problem:

privat@debian:/tmp$ strace -o ,,s /nix/store/7ys18z66aih9dwzlwkj2jynk05a3xsds-guile-bootstrap-2.0/bin/guile -c '(pk (getaddrinfo "ftp.gnu.org" "80" AI_NUMERICSERV))'

connect(5, {sa_family=AF_FILE, path="/var/run/nscd/socket"}, 110) = -1 ENOENT (No such file or directory)

Admittedly, I recently downloaded new tarballs mainly for my own new packages, and since I needed the hash, I did so using guix-download. So maybe it does not work any more since guix includes the build code from nix? It definitely did work at some point in time for my first "hello".
