No, it was compiled from a direct path (no symlinks).

I tried to compile guix from git from a path without symlinks and it was
successful as well.  So apparently the problem is with symlinked paths.

As for the symlinked directory, with your patch, "./test-env guix build
guile-bootstrap" also failed.  Then I tried to start a build process
with your patch from the beginning (from "./bootstrap" in a fresh git
tree), and I have got 3 fails (without your patch there were 14).

"test-suite.log" tells:

    ./test-env: line 33: cd: /home/alexx/src/guix/test-tmp/store: No such file 
or directory

So I think the problem with the patch is that address@hidden@/store”
directory does not exist when “`cd "@GUIX_TEST_ROOT@/store"; pwd -P`” is
being invoked.
