Weird error when getting cache.

Stream: lean4

[Wrenna Robson]

When running lean exe cache get on a fresh clone of my repo synced to the main repo, I get a bunch of errors (the last of which I have copied here but there are more like this).

This has worked fine previously. I'm trying to work out if I've changed something in my system but other than installing some objective C runtimes, I don't think I have. Any idea what could be up?

OK, no, I think it might have been a GNUStep thing because after removing a line from my .profile and restarting it appears to have fixed itself.
