You probably want to move that unless  /root/ is on a big partition.

Whatever works. I seem to have commented-out the path in  .cshrc.

IIRC  CCACHE_PATH tells ccache where to look for compilers.

csh wouldn't anyway, that's why we have to type rehash

BTW I would suggest you also set  CCACHE_HASH_COMPILER. It's a poorly
documented FreeBSD extension intended to make world builds more
cachable. I prefer to set it unconditionally. If you don't then
building world, even a point release, invalidates the cache of port
builds.
