Right, you should be able to do it from either of those, but perhaps the freebsd x86 may be easier. I would use a PREFIX other than /usr/local (or something different than whatever your actual PREFIX is) for the builds. I was looking around for my notes but can't find them. If I do find them, I'll post them. -- DE
