Please remember to include port version numbers in your ticket summaries.

We should try updating to the latest version, currently 8.313, now available from ​https://pythia.org/ (the port's homepage, master_sites, and livecheck need corresponding adjustment).

A quick search says this problem will occur if <limits> was not included, so this might have been fixed in 8.304 in which #include <limits> was added to include/Pythia8/PythiaStdlib.h. I couldn't find a proper repository for pythia, only ​a repository where releases are stored.
