You will will probably get better answers to these questions on some
FreeBSD list. At least I don't know much about FreeBSD. I have one
comment, though:

ccache only understands how to cache object files when invoked as the
compiler -- using ccache with cpp will only result in a slightly slower
build. So: it's not necessary and not recommended.

Here are some general tips on troubleshooting ccache:
