I do not believe we have enough time before 9.0R to accomplish this;
especially as I understand that there is pressure within the src committer
community to simply "throw the switch".

I think this is our only reasonable alternative medium-term.

Let me add on to this discussion the attempts to do this so far.  (Note:
I have not worked on any of them; this is all just FYI).

  PR ports/155408 [PATCH] add support for USE_GCC_BUILD to bsd.port.mk

    IMHO, necessary but insufficient.

  http://wiki.freebsd.org/PortsAndClang

    A status report on a package run vs. the clang compiler.  Some of the
    data may be stale; updates are welcome.  This is probably the best
    place to start updating data.  fwiw, it includes a link to patches
    to not only various ports, but also the infrastructure:

      http://rainbow-runner.nl/clang/patches/

  http://wiki.freebsd.org/SOC2010AndriusMorkunas

    This was a Google Summer of Code project: "making ports work with
    clang".  I do not know the status of this project.

I hope that someone will update the wiki with the latest status on the
latter two projects.
