Looks like the problem is that =E2=80=98dot=E2=80=99 is not in $PATH in you=
r case.
On my machine, =E2=80=98dot=E2=80=99 is in $PATH because I also have it in =
my profile,
and thus =E2=80=98guix graph bash | xdot -=E2=80=99 works fine.
Artyom, I think we should replace the reference to =E2=80=98dot=E2=80=99 in=
the source
with its absolute file name, =E2=80=98/gnu/store/=E2=80=A6/bin/dot=E2=80=99=
. That way xdot
would work whether or not one has installed =E2=80=98graphviz=E2=80=99 inde=
pendently.
Could you take a look?
Thanks,
Ludo=E2=80=99.

Hi Guix,
I was trying to use `xdot` to view to output of `guix graph` (`guix

Using `guix time-machine` I was able to identify the regression commit
as 2aeb9faa421635c0531d96658414e5bf288a3142
<http://git.savannah.gnu.org/cgit/guix.git/commit/?id=2aeb9faa421635c0531d96658414e5bf288a3142>
(when Ludo' updated it to 1.3). Using `xdot` within the time machine
inside the parent commit works.
I've cc'd Ludo' and hopefully we can fix this!
Warmly,
Ada
