py-scikit-image @0.19.3_1: undeclared runtime dependency on clang?

[wrohv]

Using py310, macos 12 Monterey, XCode 14.1 and 14.2, arm cpu.

Port py310-scikit-image installs correctly but any subsequent port reclaim results in

--->  Found 1 broken port, determining rebuild order
You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt: py310-scikit-image @0.19.3

After further investigation, it appears that the reclaim uninstalls llvm-14 and clang-14 in addition to some other ports. If these two are not uninstalled, then the port does not break.

[jmroot (Joshua Root)]

Could you please show the output of sudo port -vy rev-upgrade (with clang-14 and llvm-14 deactivated)? That will indicate which files are affected and what exactly they are linked with that is missing.

Sure, here it is:
