Hi all,

I'm trying to build a LV2 plugin from source.

The plugin requires libfluidsynth-dev.

Attempting to install libfluidsynth-dev produces the following error:


nico@lenovo-devuan:~/Projects/3rdParty/Fluida.lv2$ sudo apt install
libfluidsynth-dev
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libelogind0 : Conflicts: libsystemd0
E: Error, pkgProblemResolver::Resolve generated breaks, this may be
caused by held packages.

the non-dev version of the library seems fine.
