lrwxrwxrwx 2 david david 9 Jun 11 16:54 _cache/.shake.cache/5029bef81b20dfbd/0xF03C561F -> libCffi.a

_cache/.shake.cache/5029bef81b20dfbd/0xF03C561F is a broken link, but is "correct" in the sense that we want to copy the symlink as is so that _build/stage1/rts/build/libCffi_thr.a is a symlink to _build/stage1/rts/build/libCffi.a. This seems like a bug in Shake: it manages to correctly copy the symlink into the cache, but fails on the way back out.
