Comment (by barracuda156):

 I could try asking the upstream if attica can be moved to optional deps.
 Fixing Qt4 must be doable, of course, but benefit is questionable, to be
 honest, considering required efforts. It will make it easier for me to
 test some Qt4-based ports, but perhaps there is not much software which
 cannot be built with Qt5, and there is no reason to prefer Qt4 when Qt5 is
 available.
