Pace Doug's comments on how to use mergemaster, this works for me. I run my main server compiled with clang. However, it isn't under any sort of load and I haven't done any sort of performance analysis so I don't know if I'd consider clang on a high performance server at the mome= nt. Most ports compile very well using clang, but there are exceptions. Not so many though as to preclude using clang as the default compiler for por= ts.
