This is not a circular dependency. Qemu (now) depends on dtc, dtc does 
not depend on qemu.

The previous version of qemu, 9.0.2_0, did not declare a dependency on 
the dtc port and installed its own copy of dtc. The current version of 
qemu, 9.0.2_1, declares a dependency on the dtc port and uses it instead 
of installing its own copy. See 
<https://github.com/macports/macports-ports/pull/25389>.

That unfortunately means that there is a conflict that you will see when 
upgrading qemu, because its new dependency dtc is installed before qemu 
itself is upgraded. Some code to deactivate qemu in this case needs to 
be added to the dtc port. A workaround is to deactivate the old qemu 
version, activate dtc, and then activate the new qemu version.
