Hello,

after downloading the lastest git version (a0f16bb), "./autoreconf -vi" and 
configuring with
   ./configure --prefix=/usr/local/guix-git --with-nix-
prefix=/usr/local/nix-1.1
(by the way, would not "--with-nix" be a more standard choice than "--with-
nix-prefix"?) on Debian testing, "make" passes, but "make check" poses 
problems. Some tests pass without the nix-worker daemon running:
PASS: tests/base32.scm
FAIL: tests/builders.scm
FAIL: tests/derivations.scm
PASS: tests/utils.scm
PASS: tests/build-utils.scm
FAIL: tests/packages.scm
PASS: tests/snix.scm
PASS: tests/union.scm
FAIL: tests/guix-build.sh
FAIL: tests/guix-download.sh
FAIL: tests/guix-package.sh

When the nix-worker daemon is running, builders.scm hangs.
"ps -ef|grep nix" shows the following list of processes:

I tried to execute the last few ones by hand.
/usr/local/nix-1.1/libexec/nix/substituters/copy-from-other-stores.pl --
query
and
/usr/local/nix-1.1/libexec/nix/substituters/download-using-manifests.pl --
query
do not return. So maybe there is a problem with my nix installation?

guile --no-auto-compile -L /nix/store/7asnahbrlirf5dwyd16w0qpwciv3kj3z-
module-import /nix/store/q41qjkxi1h8w6qjgv6j2vcv9rf9ka4pg-

results in

starting download of `#f' from

which is a very suspicious progress message; is the `#f' normal?

I can download the file 
http://ftp.igh.cnrs.fr/pub/gnu/make/make-3.82.tar.bz2
by hand without problem. The ftp access to 
ftp://ftp.chg.ru/pub/gnu/make/make-3.82.tar.bz2 seems to be blocked by my 
current isp.

Thank you very much for your help,

Andreas
