I have been trying to install UPC on Capitan and this is what I get

In the future, please fill in the Port field and Cc the port maintainers (port info --maintainers upc), if any.

The relevant error in the log appears to be:

I'm going to guess this specific issue no longer exists, since we do have the file upc-5.2.0.1_2.darwin_15.x86_64.tbz2 on our packages server since 2018.
