Jami doesn't start libring on external distributions

[Jan Wielkiewicz]

Hello,

I don't know why, but my Jami package works properly only on Guix
System and fails on other distributions, for example Parabola. [1]

There's a comment in jami's package definition (jami):
 (propagated-inputs
  `(("libring" ,libring) ; Contains `dring', the daemon, which is
  automatically by d-bus.

So it seems dbus doesn't start libring on external distributions.

Any ideas what can be the cause and how to fix it?
