Hi! I'm writing because I'm having some issues with -CURRENT and clang in
amd64.
I first compiled latest revision at this date and everything went ok:

FreeBSD Symphony.Gl 9.0-CURRENT FreeBSD 9.0-CURRENT #4: Sun Jul 10 10:38:28

Now, a week or two later, something around libc broke.
here's the output of make buildworld with clang :

For now, remove the line:
CFLAGS+="-march=native"
from your make.conf, and try again. Clang still has some problems with
this setting, and you are most likely hitting them.
