[horde] What dependency unresolved with this problem?

[Michael Neurohr]

Hi,

I just upgraded my Ubuntu server from 14.04 to 16.04. Along with that
upgrade, it upgraded to PHP 7.0.

My Horde installation (via PEAR) works, except one problem:
When trying to open the Admin configuration for the module Horde, I'm
getting the following error. The other configs are working fine.

syntax error, unexpected 'new' (T_NEW)

I guess I'm missing a dependency since the upgrade. But which one?

Thanks,
