It's odd that ccache is mentioned and throwing an error... I thought homebrew wasn't supposed to ever use ccache.
The reason I'm even noticing & commenting on this is because I've been getting the exact same error & I'm looking for a solution. So while on the one hand I'm hearing that ccache isn't used; it is at least being mentioned and causing an error. Whether it is actually being used or not I do not know.
Can anyone shed any light on this?
