Newly cloned sac2c does not like extant ~/.sac2crc folder

I ran into this while trying to build a newly cloned sac2c on my system. I don't particularly want to blow away the other sac2crc stuff...

Regardless of that, the error message is clearly wrong. What's the best way to handle this?

This is my commit after:

commit 9e509b33 (origin/develop, origin/HEAD, NoSerialize)
