Can you comment on when this stopped working ? was it a recent update or has it not worked for a while ?

It looks like awkward_cpp is built separately now and awkward itself is noarch. So awkward_cpp probably needs to be added as a separate port that awkward depends on. Might as well switch to fetching from pypi rather than git while you're at it I guess?

Hi, I just noticed this recently. I have not used port-based awkward-array for a while.

I think jmrrot is correct. The package is now a separate pip package, ​https://pypi.org/project/awkward-cpp/#description

And it says,

It is not useful on its own, only as a dependency for awkward

Yes, it appears when v2 came out they refactor the build a bit introducing this new step.

On a quick look it is going to take more time than I have right now to get it building again, I need to figure out how to run the additional steps they now require. For one, it appears to require some utility called not which I don't think we even have in MacPorts yet...

if you only need awkward then you could for now uninstall it and install the older py-scikit-hep-awkward1 port that I kept around for some reason that now appears useful...

Note awkward1 conflicts with the newer port, so you will have to remove v2 first.

As you might have guessed I don't really use these much myself any more. I probably should make them no maintainer....
