 On a macbook air M1 I get this error

 MacBook-Air ~ % sudo port install kdelibs4
 Password:
 --->  Computing dependencies for kdelibs4
 Error: Cannot install kdelibs4 for the arch 'arm64' because
 Error: its dependency qt4-mac only supports the archs 'ppc ppc64 i386
 x86_64'.
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there is a bug.
 Error: Processing of port kdelibs4 failed

 nevertheless I have installed (I think) without problems
 sudo port install qt4-mac
