Comment:

 > On a macbook air M1 I get this error

 Yes, the error is accurate. You cannot build kdelibs4 for arm64 because
 its dependency qt4-mac does not support arm64.

 > nevertheless I have installed (I think) without problems

 Yes, you have qt4-mac installed, probably for x86_64. (`port -v installed
 qt4-mac` will tell you for sure.)
 [changeset:c1b160f0ad8c8d128313c22529d8382462dd3276/macports-ports qt4-mac
 cannot be built for arm64]. I guess kdelibs4 and all other ports that use
 qt4-mac will need to indicate that they too do not support arm64, or more
 probably the qt4 portgroup should be changed to do that so that all ports
 that use the portgroup get the fix at once.
