[Rivet] Fwd: Rivet on MAC

[David Grellscheid]

Hi Andy,

> If clang has become the default compiler on Macs,

I just checked. It's not. LLVM is the default *backend* now, but with 
the usual gcc frontend. Unless you explicitly select clang as CC and 
CXX, you'll get the gcc parsing behaviour, no more or less strict than 
before.

Looking at the log files, Juergen must have either built Rivet from 
inside the XCode IDE, or explicitly chosen CXX=/Developer/usr/bin/clang.

/Developer is definitely not on the usual $PATH.

So, I wouldn't bother with this any more. I'll try to get 1.7.0 built on 
the test machine here next. Will let you know!
