Hi Guix,
I was trying to use `xdot` to view to output of `guix graph` (`guix
graph bash | xdot -`). However, it crashed instantly with the following
stack trace:
dot: No such file or directory
Traceback (most recent call last):

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
