It is, but it is mostly an issue with not having enough resources for the prebuilt images. They haven’t released a package installer for Sonoma yet, but AIUI the minimal required fixes have been in the MacPorts core for several weeks.
There are likely to be more issues related to Apple's switch to the `prime` linker.
(I’m a port contributor and am on macports-users where this issue has come up twice. There is what I think is excessive concern about the macOS beta NDA preventing the creation of a package installer until after GA when it no longer applies. A bigger problem is the availability of sufficient build hardware as they have a smallish Mac mini multi-booting into 11, 12, and 13.)
