I was talking about clang in base, not the port.  The port will
obviously keep on installing under /usr/local, or wherever your
LOCALBASE setting points to.

The default for base is to only build clang, clang-tblgen and tblgen,
and install those in /usr/bin.  If you want the additional tools such as
llc, opt, and others, you can use the WITH_CLANG_EXTRAS setting in
src.conf(5).  Currently, we don't install shared libraries for llvm and
clang.

The version in head and stable/9 is currently the 3.0 release, with a
few small backports of post-3.0 fixes.

I will import a newer snapshot of the clang trunk into head soonish, but
I don't have an exact ETA yet.  This most likely will not be merged to
stable/9.

There's no need to edit, just building and installing world will do the
right thing.

I assume you were talking about the port?  If so, the ports mailing list
is a better place to discuss it.

Also, clang on PowerPC is not yet ready for production.  Any help there
is appreciated, but it is better to go to the LLVM mailing lists and
Bugzilla directly.
