This Library Dependency is simply wrong on Leoprad when libgcc8 cannot be built there.

A fix for this has just been pushed through [2e46a05404462e04930b612ed29d9f08ece64603/macports-ports]. You indeed found an error, and Chris has fixed it.

Many ports will not build just now, but if you wait for that propogate through, sync, and then give it a go you should be OK.

Thanks for finding this -- it took a while for everyone to see what was wrong.

Replying to kencu:

The patch set is needed by PPC Tiger as well. At least port now builds packages.
