No, not "thus".
Clang is the compiler for base and world.  There's no guarantee it works 
for all ports.  In fact, it won't build the majority of the ports that I 
maintain, so I know what you say isn't true.  You're free to provide a 
citation supporting your assertion, of course.

Sure.  But that doesn't guarantee the port builds with clang (if at 
all).  The Makefile can say, "Build me with GCC from ports".

I'm sure this is accurate.

Default, yes.
Every port will build with clang?  No.
Speculation on the % of ports that don't build with clang?  I'd guess 
%15 is the best case scenario right now.  I'd love to see some actual 
numbers though.  They must exist somewhere...
