circular dependencies in ports tree - how to fix?

Hi,

On a 15.1 poudriere jail with latest ports tree, the following happens:

[00:05:30] Sanity checking build queue
[00:05:30] Error: /usr/local/share/poudriere/bulk.sh:pkgqueue_sanity_check:27:Dependency loop detected:

How to fix, please? If not fixable in the short term, would this best be raised
as a PR in ports infrastructure, or against each port?

For the time being, I'm going to try commenting out each affected port in
the build list.
