Hi Guix,

I have defined the planisphere-report-service-type in my channel 
<https://gitlab.oit.duke.edu/jackhill/guix-at-duke/blob/363d6270d5e3505c34aa0dbfa221f64421497587/guix-at-duke/services/endpoint-management.scm>

This has been working well for me, and I have most recently been able to 
build my channel with `guix pull` with the following version of guix:

```
$ guix describe
Generation 5	Jun 10 2019 13:44:44	(current)
   guix 31775e4
     repository URL: https://git.savannah.gnu.org/git/guix.git
     commit: 31775e400e05fb05fff0de4d3ffbf9549fe20994
   guix-at-duke 363d627
     repository URL: https://gitlab.oit.duke.edu/jackhill/guix-at-duke.git
     branch: master
     commit: 363d6270d5e3505c34aa0dbfa221f64421497587
```

However, when I try to pull the most recent guix, 
aec9bb8793ca75a5bbc1731460ed4eb388764202, the build of my channel fails:

```
building /gnu/store/hycfgn8iiy9z205zi1174sgcgs0vnm5r-guix-at-duke.drv...
|builder for `/gnu/store/hycfgn8iiy9z205zi1174sgcgs0vnm5r-guix-at-duke.drv' failed to produce output path `/gnu/store/kd88fi3fsbghnscxp0ccjrzh0si055mg-guix-at-duke'
build of /gnu/store/hycfgn8iiy9z205zi1174sgcgs0vnm5r-guix-at-duke.drv failed
View build log at '/var/log/guix/drvs/hy/cfgn8iiy9z205zi1174sgcgs0vnm5r-guix-at-duke.drv.bz2'.
```

The build log is;

```
(repl-version 0 0)
(exception misc-error (value #f) (value "Unbound variable: ~s") (value (mcron-service-type)) (value #f))
```

Presumably there was some change to the mcron-service-type recently that 
requires changes in my channel, but I don't see what they could be or how 
to fix my channel.

What's going on here? What is the Guile exception trying to tell me?

Best,
Jack
